Diablosport Tuning Available For 2021 Charger/Challenger/300 5.7L and 6.4L

DiabloSport has announced 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, the company offers a wide variety of options to choose from when it comes time to tune late model cars. From PCM swaps to full PKITs that include a new PCM and tuner, the company has something for everyone. Users can expect increased horsepower and torque, better throttle response, improved transmission performance and more.

All 2021 models require a modified PCM and bypass harness before tuning can be completed.

Not legal for sale or use in the state of California. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending with CARB. Once testing is complete with California, and an E.O. number is issued, this product will be updated to 50-state legal status.
