Part Number: PCM-CHALV821
The DiabloSport Unlocked PCM is required to unlock the tuning potential of your 2021 Dodge Challenger 5.7L or 6.4L HEMI. From the factory, these cars come with locked PCMs that block performance tuning. By upgrading to this unlocked PCM, you can safely pair your vehicle with a DiabloSport inTune i3 or Trinity T2 Platinum programmer to load powerful performance tunes. With the unlocked PCM and a DiabloSport tuner, you’ll gain access to dyno-proven calibrations that deliver 25–30 RWHP gains, sharper throttle response, and improved 8-speed transmission performance for quicker, smoother shifting. You’ll also unlock features such as speedometer recalibration for larger tires, disabling MDS, and other user adjustments to optimize drivability. ⚠️ Important Notes: A compatible DiabloSport tuner (sold separately) is required to load tunes. DiabloSport modified PCMs are not compatible with other tuning brands. On 2021+ Challengers, you must save your stock calibration with your tuning device before removing the factory PCM. Follow the included instructions for a smooth install. For 2021 Challenger HEMI owners ready to break free from factory limits, the DiabloSport Unlocked PCM is the foundation for unlocking serious power and drivability improvements.
