Woke it up!

By Michael N on September 26, 2020

Noticeable increase in low end torque when in tow mode with a 34' travel trailer. The 91 octane tune really woke the big truck up! Bonus is turning off the annoying MDS!

Works great!

By bones15830 on August 27, 2021

Product works great. But just a FYI to get it to fit on a 2018 Power Wagon. You have to remove the covers on the plugs to be able to plug them into the tuner because they hit the Air Conditioning lines. But other than that it is Easy to install and program.

Great Product

By Clay on June 11, 2019

This is a great product from installation to performance no troubles whatsoever met all expectations

Works as stated

By DarylAZ on April 26, 2019

I bought this a month ago and have been working through the different power levels, and I have to say that the unit works as it is described. Gas mileage is better not outstanding but I didn't expect that big of a jump and it all depends on how heavy your foot is..... The performance settings are amazing and you really have to watch what you are doing with the increase in the throttle response. I like the change on the fly feature. I had a little bit of a challenge on the install as the 6.4L ECM is in front of the air box with minimal space but it is doable. It was worth the money to have these options and performance.

Awesome product

Please watch my review...on Destroyer1320 YouTube see what I think...

Woke up my Hemi

By Jim C on October 6, 2021

I installed this product on my 2018 Ram 2500 with 6.4L Hemi and WOW! What a difference. Pulling my 38' Travel Trailer I had way more power and increased my mileage buy 3 miles per gallon. I would recommend this product to any Hemi owner

My Pulsar

By firstclass903 on December 9, 2020

I have had the Pulsar plugged in now for a month or more and can definitely feel the difference in power. If you are buying this hoping to get better gas mileage well I havnt really noticed a difference in that. Easy to use and love being able to use it as I'm driving down the road

It really does what they say it does.

By Easydreamer on April 12, 2021

I bought a Pulsar to help the throttle response on my 2018 6.4 Ram. Totally amazed how the performance increased. Throttle response is crisp. I pull a 35 foot 5th wheel camper and I am waiting to hit road. I have put a few miles on the test to performance of the Pulsar. All I can say is WOW....!!!!! I am impressed!

Wow!

By Jon2018 on November 1, 2020

It shipped very fast even with the covid going on. installation was easy, I noticed right away a different in throttle response in performance mode. Towing mode worked awesome as well on my 2018 power wagon. I used to run one razor up north and would get 11 mpg but after the pulsar was installed I ran the same trip with 2 razors on a heavy equipment trailer my mpg went up to 13 also that was with new 35" tires instead of the factory 33" tires.

easy installation

By lizard62 on May 7, 2022

it was pretty easy to install, and easy to change modes. works great

Nice features

By Hoov on March 23, 2019

I bought it a month ago to improve on mileage and haven't noticed much difference

Easy install

By Chaosram on July 10, 2019

Super easy install and amazing throttle response. Love how easy you can on the fly tune the truck to do exactly what you want

Ram Power Wagon 2018 6.4 Hemi

By MarcMoorePC on August 12, 2021

I drive 4k miles a month. I installed earlier this week in my 2018 6.4 Hemi Power Wagon 2500. Seems that in all the modes it shifts smoother and better fuel economy especially in the eco non mds mode. It is a super tight fit against the AC lines but it's in there and so far so good.

On the Fly

By blackcash on February 27, 2019

I've had the product for about a month and I love the ability to change the setting on the fly, works great and has tremendous throttle response.

Good product

By mtymouse70 on June 28, 2019

I have a 2018 ram 2500 power wagon. Only issue was installing the product. It’s a very tight fit and instructions need to be adjusted. After installing pulsar to pcm clip cables to pulsar before re-installing whole unit to bracket otherwise it’s next to impossible to clip them on otherwise

Pulsar 2017 ram 2500 6.4 hemi

By Joe Q on April 10, 2021

Installed about a month earlier. Works well. Wish it provided the function to adjust the TPMS for,a no load ride improvement or aftermarket tires.

When it actually works its great

By Unhappy Customer 1 on March 22, 2021

I bought this and installed it, It helps the truck to tow so much nicer. Throttle response is better, seems to hold gears better. BUT... the random P0335 CKP code and engine stalling with no notice is not desirable or safe especially with a loaded trailer. I know for a fact it is the PULSAR causing this and not the truck. It would be one thing if Diablo would stand behind their product but they will not return emails or technical support requests, also I have sat on hold for hours now (not at one time) to never have anyone answer the phone. Like I said when it worked, I really liked it, but sitting in a box in my shop is not the idea spot for $500.00+ tuner. I cannot recommend this to anyone. I would just bight the bullet and buy an aftermarket PCM and get a custom tune.

works perfect

By power wagon 2500 gug on December 3, 2021

I have a 18 power wagon 6.4l Pulsar wakes this truck up. solved all my pedal lag and slow throttle response. Truck drives like it should now. No more touchy down shifts. Bought this as cheaper alternative to ecm swap with a tune. Disabled my annoying MDS as well. Easy to use.

Great product

By Ram2500hemi64 on March 18, 2021

Bought the pulsar for my 16 ram 2500 6.4l and made a big difference in throttle response and power. Super easy to install 20 minutes

Did not meet my expectations

By DJ Vee on March 3, 2019

I bought the pulsar mainly for the economy feature. Once installed, it actually made the fuel economy worst. However the performance and towing was awesome. To include the shift on the fly

Did not disable MDS

By JesseW on March 31, 2020

Bought this specifically to disable MDS on my 2015 Ram 3500 6.4L. And it definately did not do that with any of the 8 tunes selected.
