The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the ultimate tuning solution for the 2020 Jeep Grand Cherokee Trackhawk. From the factory, these high-performance SUVs ship with locked PCMs that prevent tuning. This package includes a DiabloSport Modified PCM and the powerful inTune i3 Platinum handheld programmer (PN 8345), giving you everything you need to safely unlock your Trackhawk’s full potential.
Preloaded with dyno-tested performance calibrations, the i3 Platinum delivers up to 30 rear-wheel horsepower gains, stronger torque, and refined 8-speed transmission behavior for faster, smoother shifts. Combined with sharper throttle response, these gains enhance both on-road performance and AWD traction management, making your Trackhawk accelerate harder and drive with even greater confidence.
For enthusiasts who want more flexibility, the Platinum i3 supports CMR custom tuning, giving you access to DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to bolt-ons or advanced modifications. With built-in data logging and diagnostics, you’ll be able to monitor and refine your Trackhawk’s performance as your build evolves.
⚠️ Important Note: On 2020+ vehicles, you must save your stock calibration with your tuner before removing the factory PCM. Instructions are included for a smooth, trouble-free install.
For 2020 Trackhawk owners seeking serious horsepower gains, sharper acceleration, and AWD performance improvements, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate upgrade.
