The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the ultimate tuning solution for the 2019 Jeep Grand Cherokee Trackhawk with the 6.2L supercharged HEMI.

Paired with the included DiabloSport Modified PCM, you’ll gain up to 30 rear-wheel horsepower, stronger torque, faster throttle response, and refined 8-speed transmission behavior for smoother, more aggressive shifting.\nFor enthusiasts planning additional upgrades, the Platinum i3 supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners who can create dyno-proven calibrations tailored to your bolt-ons or advanced modifications. With built-in data logging and diagnostics, you can track performance and fine-tune calibrations as your build evolves.\n⚠️ Important Note: On 2019+ vehicles, you must save your stock calibration with your tuning device before removing the factory PCM. Detailed instructions are included for a smooth install.\nFor Trackhawk owners who want serious horsepower gains, sharper drivability, and the flexibility for future mods, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate upgrade.
