Modified PCM And inTune i3 Programmer Kit;

DiabloSport is pleased to announce the addition of tuning support for the 2021 model year, 5.7L and 6.4L Hemi powered Chargers and Challengers. As Hemi fans have come to expect, we offer a wide variety of options to choose from when it comes time to tune your late model beast. From PCM swaps to full PKITs that include a new PCM and tuner, we have something for everyone. Of course the same performance benefits apply here, users can expect increased Horsepower and Torque, better throttle response, improved transmission performance, as well as end user based options! All 2021 models require a modified PCM and bypass harness before tuning can be completed. These items are included with each kit.
