Unleash the beast!

By Andrew H on June 14, 2021

Have had my pulsar installed for about a month. The performance mode is by far the best reason to purchase this mod! Unbelievable pedal response and your Hemi actually performs like a V8! Economy mode doesn’t add much. 19 combined and 22 highway with 20” tires. I do prefer Econ mode over stock however. I did not experience any issues with check engine lights, etc and am overall pretty happy with purchase. Install is a bit tight, but manageable. Wouldn’t want to uninstall too many times to return to dealer for factory service.

Works as promised

By RONALD L on June 19, 2021

I bought this about a month ago and installed it on my 2020 Ram 1500, 5.7 hemi. I bought it primarily for towing my enclosed 26 foot car hauler, with a 64 Plymouth Savoy Super Stock car, total weight about 9000 lbs. I was getting 6 MPG at anywhere from 65 to 70 MPH without it, I have the 3.92 rear gear. After towing with it for a 300 mile round trip I recieved 9 MPG at 70 MPH, 10 MPG at 55 MPH. Great increase and I'm not dialed in yet on the sweet spot of MPH, need to test between 65 and 70 MPH in one mile per hour increments. Over all I'm really pleased and would recommend it for the Ram 1500, hemis. I tried the performance mode with out a trailer and could break loose the rear tires. The economy mode added about 6 miles per gallon under 55 MPH. I need to find out what the MDS off mode will do, I really don't understand what it's supposed to do.

Don't work

By Brian A on June 17, 2021

I bought this to turn off my MDS and it doesn't work you can notice a difference in throttle response but I don't think it's worth almost 600.00 they sent me a new one and it don't work also waste of time.

Amazing Technology!

By ANTHONY C on March 28, 2019

The installation was quick, and easy! The results are fantastic...immediately you notice an increase in horsepower, and torque! Well worth the investment, and I definitely recommend this product!

Believe the reviews on You Tube!

By Dave E on January 2, 2019

I received my Pulsar on 12/17/18 for my 2019 Ram 1500. Installation was as easy as they say but you have to wiggle the connectors around a bit to get them to reach the Pulsar after it is installed. I set my tire size and diff ratio because I have the Blackout package with the 20” wheels and 3.92 rear end. Performance mode is AMAZING!! The engine growls to life, the shift points are perfect and the throttle response is stupid fast. It improved my 0-60 by at least 2 seconds and I get around 4 MPG better mileage. I have less than 3,000 miles on the truck and I expect my MPG to get even better as I get more miles on.

Best performance product for RAM

By JAMES L on May 21, 2021

The PULSAR is amazing! I have a 2020 RAM 1500 with 5.5in lift with 35in tires. Performance Mode is amazing and allows me to get 18-20 mpg highway. Well worth the investment!

Faulty

By jesse r on November 16, 2019

The tuner threw fault codes and caused sensor failures. I requested support and never got a reply.

Noticeable performance gains

By jimmy c on November 22, 2021

This is not just a tgrottle controller. My ram limited will now boil the tires. Just chirped them before. This is the real deal. 30hp at least as advertised.

Check engine

By James V on March 17, 2022

I have had model number 32453 on my 2019 ram 5.7 for over a year and all I have Dealt with his check engine lights took into the dealership after removing it and they found nothing wrong I would not recommend putting this on your Dodge ram

Really wakes the truck up

By Nicholas B on June 4, 2022

Had it on for a week now, running in economy mode daily and play with performance when someone blinks at me. Throttle response is killer and it’s got a little extra pull from 2000-4500rpm.

Outstanding add on

By Steve S on December 8, 2020

Bought the Pulsar for 2019 Ram 1500 Classic.I was shocked at the ease of lnstalation.The performance difference was really surprising.Well worth the money.

Awesome… But Nervous

By STEPHEN W on January 20, 2022

I had the previous version (prior to the redesign) and it was amazing. Then I started getting check engine lights and codes. It wasn’t really a huge thing until my truck went into limp mode and I had to go from a red light into a lot at 5 mph. Couldn’t clear codes with my reader and had to pull the negative to clear everything. BUT it woke my truck up so much that I just couldn’t stop thinking about it, like a girl that cheats but it was just so good you almost don’t care. So, I got this new one in an attempt to mend our relationship. It woke my truck up just like last time but this one’s got heels. The old version would fight and deactivate the cylinder deactivation every time it came on in the old version. This one limits the gear to 8 so it doesn’t ever kick on. I’m super happy with this one just praying she doesn’t cheat and throw codes. 4 stars only because I’m scared. Hasn’t so far and it’s been a few weeks so FINGERS CROSSED!

Best yet!

By Steven L on November 8, 2019

I have bought programmers for many vehicles in the past and to date this is by far the best one yet. The performance is by the seat of your pants noticable. After driving my truck my buddy is ordering one for his as well. Really like how easy it is to change settings from steering wheel cruise control and everything is displayed in dash cluster. Yes I would recommend to a friend.

Not all features work

By Christopher S on May 6, 2021

Bought this for my 2019 Ram 1500 Classic. Was able to program for the 35’s I am running. Once it was finished programming the truck fired right up and I thought all was good. I have always ran 93 octane fuel in truck so switched it to perf mds/off mode and truck was running good till I got up to speed and truck shifted into mds mode which is real noticeable due to the muffler delete I had performed. So at this point I sent my first email in to ask what was up. Return email basically said put it into a mds/off mode and it will disable it. Ordered an update cable and updated unit. Still kept going into mds mode. After taking pictures and sending another email to ask what’s up and what needs to be done I am a month now without so much as a reply. Product works great with what works but customer service needs to be worked on. Would not recommend this product to anyone till customer service is improved and and the bugs are worked out.

This has great features

By William H on January 21, 2019

I bought about 3 weeks ago and installed it and wow, what a difference it makes. I really enjoy driving my truck. And if you have to take your truck in for warranty work just take it off and there is no trace of it ever being there. Y have 8 different settings and you can change them while driving which I think is great.

More Horsepower!!!!

By Zahay G on December 3, 2019

I bought the Pulsar about a month ago. Installation was quick and easy with straight forward instructions. The throttle response and additional giddy up was noticeable, making for a more enjoyable driving experience!

Great product!

By RonG on July 27, 2019

Installed the Pulsar on my '19 Ram Big Horn about a week ago. So far I am loving it! The throttle response is is great! No more MDS. The only negative is the price. Kinda pricey for what it does.

Nice upgrade

By TonyB392 on July 17, 2022

Easy install working great so far no problem very easy to change features on the fly I feel they worked out all the little Kinks that the first ones head

Superchip

By ACDC713 on March 20, 2021

Been waiting for the Pulsar to come out. Easy install. Easy to use. Really wakes up the Hemi.

Performance setting makes my driving like sport ca

By IgorAfichuk on December 21, 2018

Driving on Pulsar about 2 weeks now - very happy!!!

mr al

By al48 on September 12, 2019

just put it in today 9/18/2019 it works good a lot better

Great tuner

By Amit on June 21, 2022

Works great and gas mileage is good. Power is great too and instant change on tunes are awesome.

Excellent Upgrade!

By Bad BB on April 6, 2021

I wanted to add a little more power without having to change the PCM on my new truck, thought I'd give the Pulsar a shot. Very pleased with the performance, easy install, and the fact that I can finally disable that annoying MDS!

Promises kept

By Behr65 on April 8, 2019

Easy to install (20 minutes) and take off. Performance & mileage difference is noticeable right from the start.

Great simple power adder/ tuner

By BFLANDERS on January 11, 2020

As a 3rd time diablosport owner I can still say I'm very pleased. I take the MDS off of all the newer HEMIs I've owned and the Pulsar did that and way more. It'll literally smoke 37s on 6" lift all the way down the road. I definitely recommend

Simple to install, truck performance is great

By JoshRivenbark on December 7, 2018

Quick and easy to Install. Dramatic increase in performance with the truck. Easy to use interface.

Better than expected

By BBurke73 on February 6, 2022

I got mine about 2 weeks ago and the throttle response is significantly better and in performance mode I haven’t noticed any significant loss in fuel mileage. However I have only ever used top tier fuels and premium grade only. It works great and would recommend this to anyone with a new Ram..

Great little in line tuner

By rebel_50_tuxedo on July 10, 2022

I bought this a few months ago for my 21 Rebel 5.7 NA Installation was easy, if you can make a sandwich you can install this. The mode toggling feature was easy to get the hang of. It does all it claims to do. Saves gas in econ mode. Really picks up in performance mode and let's be honest, that's where I'm living life.*** What this is not*** is a custom written tune, it is not the best electronic tuner you can buy. ***But For The Price!!! It's amazing!!!***

Good

By Deez nuts on May 22, 2022

Truck won’t let me go over 110mph now and that’s a issue

Great product!

By Britt on May 27, 2019

A great product! Easy to install , and super easy to use. The power gains are instantly noticeable when in performance mode!

DO NOT USE THIS PRODUCT!!!!!!!!!!

By Harry Banatte on June 2, 2021

After having this tuner installed in my 1500 2020 Ram. Im now having problems with transmission shifting correctly! I have many codes that are stuck in my computer. Service Electronic stability control message comes on and I have to turn off my vehicle then back on inorder to move. No one has returned my call. My truck is brand new just hit 25 thousand miles.

Definitely makes a difference

By ChrisR on February 1, 2022

Recently installed the Pulsar on my '22 Ram 1500 and I love it. Doesn't add anything crazy, but the power it does add and killing the pedal delay makes this truck so much smoother. Being able to select the tune on the fly is a huge selling point. Very satisfied

Much better than I expected.

By Irish on July 21, 2019

I was semi hopefull when I purchased the Pulsar. But my mind is blown. The ability to change tune on the fly is amazing. My main purpose was to use the Stock/ MDS off. But I have quickly become a fan of Performance mode. You really feel the extra kick. Well worth the $$$

Good features

By Cody31 on March 28, 2021

Changed my tire size throttle response is awesome fuel mileage came up about 1.6 mpg little pricey for what it does for me but overall happy with it

Great product

By Beast on May 25, 2019

Good product..... ................................

Worth it

By DaveRam1982 on January 8, 2019

I just got a 2019 ram with the hemi and if you have ever driven one, you would understand when I tell you about the lack of throttle response and poor shift patterns. After the pulsar it is a whole different truck. Much more responsive and quicker to react. I use the tow mode mostly. Performance mode is super touchy!

Fuel Economy

By DKiser on July 21, 2022

Love the function of how this works in the cluster. Fuel economy up 3 points from 14.1 to 17.3mpg already. Performance? Haven't romped it yet. Stay tuned..

Turned my 2020 Ram 1500 into a BEAST

By DonRob87 on March 26, 2022

This was a perfect addition to my Ram. Accompanied with my installed K&N High Flow Cold Air Intake and Outlaw Direct Flow Muffler, this tuner made for a perfect trio to unleash my Ram’s full potential. Installation was very easy and straightforward (took me less than an hour) thanks to clear and simple instructions. The 8 levels are intuitive and I love how I can easily control and switch between them using the cruise control keys and see it right on the dashboard panel. I typically keep it in Economy MDS Off (this level maximizes my fuel economy which is the reason I bought this in the first place; I’ve gained an average of 2.5 mpg; now I average around 20mpg city with all 3 performance mods) but several times I threw it in Performance MDS Off which REALLY hauls A! Throttle response is flawless and the horsepower and torque boost adds a fluid punch. Even in the tow levels, you can feel the increased torque. As far as the MDS Off levels, it perfectly turns off MDS which makes a huge difference in performance as turning off the 4 cylinders is counterintuitive to performance if you have increased airflow such as with a Cold Air Intake and/or Direct Flow Muffler installed. And as an added benefit, NO MORE DRONING!! This tuner is well worth the investment and a great addition for fine tuning and maximum performance on your Ram especially if you already have performance parts installed.

Great purchase!

By DW Rabbit on November 15, 2020

I have had this product for about a month and it works as advertised, love that the controls are built into the steering wheel and can change on the fly.

Excellent

By Bin besher on December 11, 2020

Really is excellent and I get the power full power

Never going back to stock!

By enads on June 19, 2019

Immediate pedal response and horsepower increase. Best money I've spent on my truck. Even in performance mode I get better gas mileage than stock.

Easy power for the money.

By Eastin357 on December 7, 2018

The only negative thing I have to say is. When you are driving down the freeway the mds kicks on for a blink of an eye then the pulsar shuts it off. So I always have to hear the engine fluctuate in rpm every 3 seconds. So I have to do my normal trick and put the gear selector to 8th so the mds stays off. Other the. That it really wakes the truck up. You can feel the power difference in every mode and the throttle gets more touchy as you go up in power so be careful.

Pulsar 2021 ram 1500

By Everyday0501 on January 27, 2022

Bought this about month ago because I drive all over the East cost for work and wanted a little more fuel mileage. This changed it 0% only thing I got was throttle response which is very good. Other then that 0% change. Bad investment.

AMAZING!!!!

By 45wantz on February 7, 2019

You wont believe the results. Order one now you will NOT be disappointed.

Just be ready.

By Brad on February 8, 2019

Installed on 2019 Ram Classic Express with 5.7 Hemi. The results were very noticeable. I normally keep it in the "Stock No MDS" mode. I also use the "Tow No MDS" mode when towing my 22' Tidewater. However; just be ready when you try the "Performance" mode. Acceleration is ISTANTANEOUS and will set your head back. The HP increase is also noticeable when in "Performance" mode.

Just be ready.

By Brad on February 8, 2019

EASY!

By GMKTM on January 16, 2020

Just got my nerve up to install this last weekend, instructions made it seem way more complicated than it was. Once I got into it, everything made sense and was very easy to do. And WOW! Installed a K & N Cold Air system at the same time and now when you select the "Performance Mode", it runs noticeably better! Or can just leave Stock, economy or Tow; and with or without the MDS system. Very simple to scroll between settings using the cruise control buttons on the steering wheel. Very simple well thought out system!

Great features and add horsepower to my truck.

By Goner on March 25, 2019

I bought it few months ago and I very happy with it!!!

Disappointed

By jdgray12 on August 25, 2019

Bought this about a month ago and at first it was great. Huge improvement in throttle response. I did input my tire size to calibrate the speedometer and it didn't work. A couple days ago it caused a fault in my electronic stability control and threw an engine light. I had to remove it to get rid of the fault. Now I have a new tuner sitting in my garage, collecting dust. Maybe I just got a bad unit.

Seanless. No CEL, no problems. Great features

By Gtarzan on November 7, 2021

I bought this a few weeks ago and, after reading reviews about the problems experienced in 2019, I reached out to The Diablosport team to verify compatibility with my 2021 Ram Laramie. I was assured that it was compatible. Installation is simple and straight forward. The results are amazing. Crisp throttle response in both tow and performance modes. Turning of MDS is just the icing on the cake. The ease of use via steering wheel mounted controls is a great feature. Truly having your cake, and doing burnouts too. After use of Diablo handheld tubers on my last three GM pickups, the company has earned my trust. Keep making great products.

Doesn’t work as advertised

By Howell on January 13, 2022

Purchased for the ability to disable MDS. It does not disable MDS as advertised.

Pulsar programmer

By Hurkybird on February 25, 2019

Easiest hookup I've deleted with.... Performance mode is fun!

Love it but

By Jtfman on February 12, 2019

I put this on my truck and love it. But now I have a recall and I have to take it off so I can get my squeaky breaks fixed.

Love it but

I put this on my truck and love it. But now I have a recall and I have to take it off so I can get my squeaky breaks fixed.

Awesome

By Genuts on April 26, 2020

This thing is everything it claims to be. It will make you smile every time you touch the pedal.

Awesome results!

By Big John on January 19, 2019

I have been running this for about two weeks now and I’m really happy with the results so far. Gas pedal lag is no more in all positions . While in Performance all I can say is wow and in economy I have seen a little gain in mileage. Really happy all around and very easy to install.

Basically a Pedal Commander on steroids

By Jeh0131 on December 20, 2021

I got the Pulsar about 2 weeks ago, and stay in economy mode mostly. My avg MOG has went up 1.5 miles, which is decent. One thing to remember is the Pulsar is NOT a tuner. It does NOT remove speed limits, and you can’t specifically tune like u can with a legitimate tuner. I can feel a difference in power from stock to performance, but not “30 hp” as it states. Maybe 4-5 HP at the most. Easy to install, and throttle response changes, but just spend the extra money and get a real tuner.

Great add to my RAM

By Jamie1974 on May 8, 2021

I bought it and installed the same day I got it . Then drove 1300 Miles went from 15 Mpg to 18 Mpg. Throttle response was amazing over stock

Must have if you have larger tires

By Monty on January 25, 2021

Had this Pulsar for almost a month now. So far enjoying it. I have tried out the different modes; i'm not a fan of economy mode. Tow mode is probably the best as far as drivability is concerned. Especially the fact that my truck has 35s, it changed the shift points just right, and added a little bit of sensitivity to the throttle. Performance mode really wakes up the truck and makes the throttle very sensitive. The shift on the fly feature is really great too. My only issue is that anytime I have to go to the dealer, I have to remove the Pulsar.

Easy to install

By KellumJ on February 17, 2019

Overall great product. Only complaint is the economy vs stock modes. Dont notice any change at all. Performance mode is awesome though!

Like it

By Dave doodog on September 30, 2019

Install was a breeze Set up is easy Can definitely feel the difference in all the modes The Eco message still displays , not sure if it's supposed to or not,

Better than expected.

By Crimson Wolf on March 3, 2019

100% worth it. performance mode blows the tires right off with instant throttle response. truck very undriveable. I LOVE IT. economy mode is no joke too LMAO.

Unhappy

By Khram2019 on June 20, 2019

So far I cannot update by computer, tried the update agent 1.0 for windows, tried to register my Pulsar, serial # is not marked on product as serial number, which numbers do you want ? Installed in truck, computer with update agent will not recognize its installed, have had a couple times truck died at a stop sign, then acted up again, not sure I'm very happy yet.

Phenomenal

By Mazzamania3D on July 22, 2021

Super easy installation! Unbelievable throttle response in Performance mode. I’ve had vehicles with pro chargers and turbos, so I was shocked on how much this little chip produced! A must get!!!

Performed as marketed/Easy to install

By ButtHoleSurfer on March 5, 2019

Performed as marketed/Easy to install. Great product.

VERY Happy w/my purchase

By Lrobbi on September 15, 2018

So I got PULSAR for my 2019 Hemi and installed it the same day. Installation was a breeze and easy to understand - you can also simply follow the video. 15min later I was out for a drive, and OMG. I put it in Performance mode, the smile on my face says it all. THROTTLE Response is amazing... the difference is very noticeable. - I promise you, you will be happy. A great product, I hope in the future if I go to a Super Charger for this 2019 Hemi... I can still use this - I love how easy it is to switch on a fly. thanks Lewis R.

Great features

By Magpie on January 29, 2021

Very easy to install, it's definitely worth the money.

Some cool features!

By bellanator on March 19, 2021

I installed this in my 2021 Ram 1500 Laramie with the 5.7L Hemi E-torque. Super easy install. I did buy the USB-OBDII cable so I could update the Pulsar software if need be. It did come already updated but I'm glad I can update as new software releases become available. I did have issues after the install with the 12" navigation system....I lost alot of the settings apps and control of the heat/cool system which is controlled from the nav system. It was like the nav system reverted to the software for the 8" display. Everything just looked different is how I'd explain it. After a few hours, the system updated itself and everything is back to normal. The inline tuner is awesome that you can make changes on the fly and it's integrated with the instrument cluster display. I really wish they would add the ability to defeat the speed limiter and Auto-off feature. Maybe that will be available down the line. I'm really happy with the instant throttle response...oh my!!! And I'm getting 3 miles per gallon better fuel economy with the "Performance" setting. Went from 16.5 to 19.5. A worthy purchase indeed.

Power

By Lonewolf1204 on March 14, 2019

Notice right after installing pulsar a great deal of power when I accelerated . Also I gained from 14 mph. To 16 to 17 mpg.my truck is so much more responsive

Love the Pulsar

By Tdub12 on November 11, 2019

Bought for my 2019 Ram 1500 4x4. Running 35x12.5x20s. Had to tweak the tire size to get the correct speedometer reading but it’s painless to do so no big deal. Throttle response in performance mode is ridiculously good. Night and day from stock mode. Very impressed. No change in economy mode but with tire size I wasn’t expecting any help there. Curious to see tow/haul benefits when able to. If you want to unlock some extra gitty up, get the Pulsar. Easy to install. Being able to change your mode on the fly is pretty cool too.

Performs better than advertised.

By Mikey1 on September 27, 2018

You will not be dissatisfied with the chip. Super easy to install and the ability to change settings on the fly is awesome. Headed down highway, switch to economy. Pull into to town and need to show some muscle at the red light, switch to performance mode. This is the best chip I have ever installed.

On the fly is a novel concept...but

By RamRebel64 on January 6, 2020

1. I installed this with alignment issues at first and broke a handle to my pcm. 2. Performance mode is real jerky out the gate. 3. Economy mode makes no difference wether I’m heavy or light on the pedal.

2019 1500 pulsar

By Miller33 on May 3, 2021

Super easy install and instantaneous power!!! Absolutely love it. Gonna need tires soon

Great product

By Moorebobby98 on February 10, 2020

I bought the pulsar kit for my 2019 ram limited and it makes a huge difference when you are in performance mode. When I first put the product into the truck I almost sent it back because it changed all of my screens to a basic look. I called Diablo up and they told me everything will come back apparently They reset themselves once the battery is removed. Everything came back. Thankfully my only complain is that you can’t remove the speed limiter with this kit. That was kind of a bummer. Other than that 100 % would recommend

Pulsar on my 2020 ram 1500

By mrmoo31 on February 28, 2021

I've been waiting for this product for a whole year! Finally the pulsar for my 2020 ram 1500 is available. Easy install and wow!! The hemi power was unleashed! Love the throttle response too. I also have 35 inch tires and was able to calibrate speedometer.

Great product

By Mr Wish on August 21, 2021

Works just like it says and very quick and easy to install

Over priced pedal commander

By Msuttie14 on March 30, 2022

I’ve had this for a couple weeks now and I am not pleased. It’s a over priced pedal commander with a couple extra features. I should of went with the trinity instead.

Awesome

By Shilup on April 12, 2021

I bought this about a month ago and now in performance mode there is a big difference in take off and pick up speed and in economy mode I get 2-3 more mpg.

This will get you in trouble.

By NLB572 on January 16, 2020

Install my Pulsar a month ago. It's changed the truck 100%. The power and shifting of the transmission is unbelievable. The sound of the exhaust system you can even hear the power. Gas mileage has improved 105 MPG.

save your money. wait until they get the bugs o

By rocktoza on August 23, 2019

Nothing I have used diablo tuners in the past and they worked better then any other, I do think they rushed the pulsar to market and someone will get injured do to what happens with some dodge rams like mine with it going I to limp mode, taking off by itself, check engine light coming on, etc etc.

Hi cost for little value

By 89FC619 on May 17, 2022

Great little chip and integrates seemlessly. You really are paying for the integration, not so much the gains. Still a fun little edition pending you have the cash to blow. If not, a 99.00 pedal camander will do the same thing

Chirped 3 gears on test without trying

By Johnny gee on October 20, 2018

Buy this tuner if you have a new 1500 it will make your Hemi run like it is supposed to easy install and night and day from stock to preformance mode. Very happy with this tuner and can’t imagine going back

Not what I expected

By Phil7027 on December 15, 2018

Overall I am not completely disappointed but not at all what I expected. Eco mode is completely useless, you have to put your foot to the floor to even accelerate from 50-60mph on the highway, performance mode only seems to have added throttle response and not much different. Actually feels slower from 3500-5000rpm. Shifts points are better in performance mode, but shift speed and firmness at WOT are the same as stock. Great features that you can change tunes on the fly, but it only seems to affect throttle response and nothing else. personally I would not waste the money, better off waiting for a custom tuning option

Love it!!!!!

By Pepdeez on August 12, 2019

Best bang for the buck. Easy install, easy setup, let it rip.

Great product!

By ProEMTPFF on November 13, 2018

I have had this for a few weeks now and I'm fairly happy with the canned tunes. I'm disappointed that the "speed limiter" can NOT be turned off or adjusted higher. Loved the MSD off option! I hope Diablosport continues to make tune improvements, have continued support and development on this product.

It works as advertised

By Detroitram on February 6, 2019

I blew away every f150 that tried to bully the RAM at the traffic light so this product has earned my respect.

Parking sensors not working after install

By Raulibarra3 on April 6, 2021

As soon as I installed, parking sensors stopped working. I've called twice for support, did what I was told, not able to fix it yet. I'll give Diablo a third call if that doesn't work, I'll return it.

Tire size and parking sensors

By LiveWire2022 on May 29, 2022

Has any update fixed on 2022s when you change the tire size, the parking sensors quit working?

Shift to Performance on the Fly

By lacydogg1 on April 21, 2022

All worked well with the product, but tried to put on 2 year old truck. Cheap RAM plastic was brittle and broke so had to modify when I put it back. Product was solid and worked right away though!

Wow!

By Harley 15 on February 25, 2019

Got this month ago,and made hugh difference in power,easy to use and install,put this on my brand new truck and glad i did,

Pulsar - Such a difference

By Rob M on April 26, 2022

I ordered around a month ago. The first one had an issue, but customer service immediately despatched another. Fitting is not the easiest, and takes a little patience as the bolts become 'hidden' by other engine components. My PCM cables were just about long enough but it was a squeeze. The difference in engine response is immediate (Performance mode on), and it brings a smile to my face. Its not TRX or Raptor performance, but it beats most other trucks off the line.

Great Product

By RonK on January 2, 2019

This is a great product. There is a very noticeable difference with each tune. I get a little better mileage in Economy. The Performance tune is awesome and make the truck that much more fun to drive.

Great features Easy install

By MrKada on March 15, 2019

The product was a simple and straight forward.. Just wasn’t for me the only thing i really felt was throttle response was improved but as far as MPG I didn’t see a difference

Easy install

By Rugman on March 6, 2020

Love the performance and throttle response I now have when in performance MDS mode, I haven’t use any other mode as of yet. This next week I’ll install cold air intake. My 2019 Ram 1500 5.7 already has Borla cat back exhaust. Now with the Pulsar really sounds great! I’m very please with this purchase.

4+ MPG Street, 3+ MPG towing, More Power

By RyanTRamus on July 15, 2020

I've been driving this for about a month now. I find I do the opposite of what some people suggested doing, and get the most efficiency out of my 2019 Ram Classic. In town, I use eco mode. The throttle response is slower and smoother. On the freeway, I use performance mode, as it responds better at higher speeds and shifts immediately. My first tank of gas took me from 15 mpg average, to 19 mpg average. Towing a decent load, I was averaging 11-12 mpg. Towing that same load with the Pulsar, I got 15+. It rarely shifted lower than 6th gear, and only went down to 5th on the steepest hills. Before, I was shifting down to 4th and killing cruise control just so I didn't rev so high. I put the manual gear selector in either 6 or 7 and pulled 70-75 mph with no problems. My advice is get it. Be careful of performance mode in town, because you can't push the gas soft enough not to screech the tires.

Throttle Response

By Seaducks on May 24, 2020

Super easy install and very easy to change between levels. My 2019 Ram Classic has also been upgraded with vararam air grabber and cat back exhaust, so I can’t say what the programmer has done alone. I will say it has great throttle response now and more “seat of the pants” power. I’m running 93 octane as well, so there are a lot of variables to throw in the equation. I can’t give it an excellent rating because I cannot say that it is the reason for all the gains. That is not Diablo’s fault.

Ez to install

By Sd1771 on January 3, 2022

I installed this a couple of weeks ago and so far the biggest noticeable difference I see is the throttle response… at first the electrical I thought were messed up as my radio did not work but then the next day everything was fine as I think it takes sometime for system to adapt… Other than that I’m looking for increases in mpg but it’s not giving me the 2-3 mph I was hoping for..

Added Performance

By SN391 on May 13, 2019

I like the added performance and easily selected with the touch of a button

Does work somewhat but not worth it

By staley on April 23, 2022

I've had installed and drove 100 miles. I did see approx 1 mpg better hwy on performance mode and it did seem to have more throttle/shift response but the backup/front sensors are disabled now. I don't have confidence in the unit so I'll be returning. Also I inputed the exact tire size in inches and the correct axle ratio and it's 3 mph wrong in the opposite way now.

Emissions code popped up could not clear

By Shrek Henry on June 10, 2022

Bought an installed with instructions emissions called popped up could not clear return not good trucks 2 years old never had an engine code

Makes the truck quicker but terrible side effects.

By Blackram_UK on February 11, 2022

I fitted the Pulsar to my 22 RAM 1500 Laramie. It was a simple procedure. Everything seemed to work, I set my tyre size to 35" and took it for a test drive. Immediately noticed a warning - parking sensors were not working. I thought that they may come on them selves after a while. No luck. Tried everything. No parking sensors. Checked wiring, checked for fault codes, nothing. Just seems to break your parking sensors. Maybe this is an issue with the 22 model ? I have emailed Diablo Sport but no response. Would give this a much better review if my parking sensors worked.

Pleasantly surprised

By skeptical on July 13, 2019

I am the master of skepticism about most things, especially products like this. Surprised I actually purchased it, but the new RAM was just lacking a bit. WOW,,, easy install, instantly could tell the benefit and differences across modes. Definitely a good product and worth the purchase.

Great product

By Tj1500ram on January 23, 2019

I am very happy with my pulsar. Easy install and works great. If your thinking of getting one do it.

Pulsar for my 2019 Ram 1500 Limited

By T Savage on January 16, 2019

I purchased the Pulsar for my 2019 Ram Limited and very happy I did. The truck already had decent acceleration but the difference in Performance mode is amazing. Great response, noticeable difference and easy with the shift on the fly ability.

Awesome!!

By Wags78 on November 27, 2018
