Increase your 2015 Chrysler SUV’s performance with a DiabloSport Tuner! Our R&D team has found a solution for the Jeep Grand Cherokee or Dodge Durango that allows you to add additional horsepower and torque over your factory tune!
We also unlocked a wide variety of adjustable performance parameters during our R&D process. These options give users control over their SUV unlike any other performance upgrade on the market. Users will be able to easily calibrate their vehicle for aftermarket wheels, add or remove timing, increase or decrease fueling, as well as raise the rev limiter and speed limiter.
Through hundreds hours of dedicated R&D we found a solution to tune the latest model Chrysler vehicles, but it’s different than a standard plug-and-play tuner. To unlock the vehicle’s untapped potential, you will need DiabloSport modified PCM that you can swap with your factory computer by just unscrewing a couple of bolts. Once you have installed the Diablo modified PCM, you can tune your SUV for better towing power, street performance, and increased mileage!
We can provide you all the necessary equipment (PCM and Tuner) that allows you to install a tune on your vehicle. Here is how it works:
Provide us with your car’s VIN and Odometer mileage using this order form and we will send out an aftermarket PCM and any tuning devices you need to tune the vehicle. You will replace the truck’s stock PCM with the aftermarket Diablo PCM through a simple process that should only take about twenty minutes. Once you have replaced the factory PCM, you can install a tune with your DiabloSport tuner and you are ready to go! If you need to go to the dealership for service work, re-install your original PCM and the dealer will not be able to tell that you have done any modifications. Basic installation instructions for this process can be found here.
There is also an option to send your truck’s current PCM into DiabloSport for us to reprogram it for $200. While this option costs less, there are some important things to note about modifying your existing PCM. The first and most important is that sending your factory PCM in for the unlock service could take between 3-5 business days. Additionally, if you unlock your factory PCM and do not have a spare, you may have issues at the dealership if they need to re-flash for any reason. We always advise that you use the option for an additional modified PCM so you have more options. If you’d like to send your PCM in for unlock service, click this link.
The tune selections for the 2015 Dodge and Jeep SUVs are based on the grade of gasoline you run. For the best results, always run the highest-grade gas in your area along with the DiabloSport tune associated with that gasoline.
