DiabloSport does the hard part for you, by developing clean, powerful tunes for 91 and 93 octane fuels. Then we give you a host of user defined options, like the ability to disable the top speed limiter or recalibrate the speedometer for different tire sizes. Looking for every last drop of performance? Built in datalogging allows you to see data, like timing or knock retard,  by viewing the logs on our Dataviewer PC software,  No matter what you do with your Charger, Challenger or 300, DiabloSport offers a tuning product to fit your needs!

All 2015 and newer Dodge/Chrysler/Jeep/Ram applications require an unlocked PCM before tuning. We make this easy with multiple options, including tuners that include a PCM swap, or kits that include a new, unlocked PCM for your car. No matter which option you refer, we’ve got you covered!
