2015-2016 Charger, Challenger and 300 RT/SRT8 Tuners

Power Up Your 2015-2016 SRT8/Scat Pack Challenger, Charger or 300

Our performance programmers create a massive power boost on your 2015-2016 HEMI 5.7L or 6.4L Chrysler 300, Dodge Charger, or Dodge Challenger! Our R&D team has found a solution for the V8 HEMI cars that allow you to get an additional 15 HP & 20 Ft. Lbs of torque in less than an hour!

Technology = Power!

As the industry leader in HEMI tuning, you can expect no less than the best from our engineering team when it comes to your Mopar. Our tunes for 93 octane have been dyno and street proven, and they make your car drive like a dream! We made g2015_sonic_14_tuned_dyno_resultsains of 15 HP and 20 TQ – and that’s on a stock car! If you have modified your ride, our inTune & Trinity tuners also let you adjust key vehicle parameters on your HEMI. Calibrate the speedometer for larger tires and gears, adjust idle RPM, dial in your throttle response with “throttle booster technology”, and you can even modify performance parameters like timing/fueling/idle and more!


Through hours of dedicated R&D on the newest Chrysler cars, we found a solution to tune them- but it requires and Diablo Modified PCM. To unlock your car’s potential, you will need an Diablo Modified PCM that you can swap with your existing factory computer by just unscrewing a few of bolts. We offer Diablo Modified PCMs on our site for purchase, or you can unlock your PCM by contacting us and sending it in for an unlock service. Once you’ve installed the Diablo modified PCM, you can tune your car for any combination of aftermarket performance mods, or even add power to a stock vehicle!

Get a Spare DiabloSport Modified PCM for tuning

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 Diablo Modified PCM and any tuning devices you need to tune the vehicle. You will replace the car’s stock PCM with the Diablo modified 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.

Send your PCM to DiabloSport To Unlock it

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 reflash 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.

Pre-Loaded Performance Programs

The tune selections for the 2015+ Chrysler HEMI Cars depend on the type of gas you want to put in the tank. For best results, we always recommend running the highest-octane gas available, and running the tune associated with that octane rating (ex: 93 octane, 91 octane)

93 Octane Performance Tune +10-15 HP / +10-20 TQ

Designed for the maximum power, economy, and drivability gains, on 2015-2016 300, Challenger, and Chargers with a 5.7L/6.4L HEMI engine. Users should run a minimum of 93 octane in their gas tank to see the best power gains.

91 Octane Performance Tune +8-13 HP / +8-18 TQ

Designed for power and economy gains while running 91-octane gasoline. The power is a little less than the 93 tune, but offers the same great drivability gains on your 2015 or 2016 5.7L/6.4L car.
