Compatible with 2019 Jeep Grand Cherokee Trackhawk - 6.2L

Part Number: PKITTHAWK19-I3

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. From the factory, these SUVs come equipped with locked PCMs that block tuning—but this kit provides everything you need to safely unlock your Trackhawk’s hidden performance. The inTune i3 Platinum handheld programmer (PN 8345) comes preloaded with dyno-tested tunes engineered for the Trackhawk platform. 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. For 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. ⚠️ 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. For 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.
