The DiabloSport PCM-HAWK21 is a modified PCM for the 2021 Jeep Grand Cherokee Trackhawk with a 6.2L engine. It enables tuning with compatible DiabloSport tuning products; a tuner is required to install performance tunes.
Factory PCMs on these supercharged HEMI vehicles are locked and block tuning. This professionally unlocked PCM is programmed for the vehicle and enables compatible DiabloSport tuning products.
When paired with a compatible DiabloSport tuner, the manufacturer states gains of up to 30–35 RWHP, along with improved throttle response, stronger torque delivery, and refined transmission behavior for quicker, smoother shifting.
A DiabloSport tuner is sold separately. Modified PCMs are not compatible with other tuning brands.
For 2019-and-newer vehicles, save the stock calibration with the tuning device before removing the factory PCM, and follow the included instructions carefully.
