DiabloSport is pleased to announce tuning support for the all new, 2021 Jeep Wrangler Rubicon 392 models. We’ve spent some serious time with the Rubicon 392 calibration, in an effort to make this amazing vehicle even better. With gains of 14 rear wheel horsepower over stock, we managed to make the 6.4L Hemi even more powerful. Improved throttle response and shift feel are additional benefits of the provided tunes. Support is available on the inTune 3 and Trinity 2 product lines, and include the required gateway bypass module, as well as the necessary PCM swap options.

They focus on making the maximum power, drivability, and fuel economy gain on late model fuel injected vehicles.

Quality and Performance You Can Trust

DiabloSport is made up of a team of people who are horsepower junkies by trade- making the biggest possible power gain is why they go to work every day.
