Diablosport DiabloSport Modified PCM Only 2021 6.2L Trackhawk PCM-HAWK21 | PCM-HAWK21

The DiabloSport Unlocked PCM is required to tune your Ram TRX, Dodge Durango Hellcat, or Jeep Grand Cherokee Trackhawk. From the factory, these supercharged HEMI vehicles come with locked PCMs that block tuning. By upgrading to this modified PCM, you’ll gain the ability to pair your vehicle with a DiabloSport inTune i3 or Trinity T2 Platinum programmer and install dyno-proven performance tunes.

When paired with a compatible DiabloSport tuner, this unlocked PCM enables gains of up to 30–35 RWHP, improved throttle response, stronger torque delivery, and refined transmission behavior for quicker, smoother shifting. These upgrades make your TRX, Durango Hellcat, or Trackhawk feel sharper, more powerful, and more responsive in every driving scenario.

⚠️ Important Notes:

A DiabloSport tuner (sold separately) is required to install performance tunes.

Modified PCMs are not compatible with other tuning brands.

On 2019+ model year vehicles, you must save your stock calibration with your tuning device before removing the factory PCM. Follow the included instructions carefully for a smooth installation.

For Hellcat, TRX, and Trackhawk owners who demand maximum performance, the DiabloSport Unlocked PCM is the foundation for unlocking serious horsepower and drivability improvements.
