Product Details

The Diablo Sport Trinity T2 Platinum + Unlocked PCM Kit is the ultimate tuning and monitoring solution for the 2015 Jeep Grand Cherokee 5.7L and 6.4L HEMI

These SUVs come with locked factory PCMs that prevent tuning-but this kit includes a Diablo Sport Modified PCM and the advanced Trinity T2 Platinum programmer, giving you everything you need to safely unlock your Jeep's true potential.

Preloaded with dyno-tested performance calibrations, the T2 Platinum delivers 20-25 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined 8-speed transmission performance for faster, smoother shifts

The kit also enables MDS (Multi-Displacement System) disable, letting you run in full V8 mode for maximum power and drivability

For those planning upgrades, the Platinum T2 supports CMR custom tuning, allowing you to work with Diablo Sport's nationwide tuner network to create dyno-proven calibrations tailored to your build

With built-in data logging, diagnostics, and performance testing, you'll have full insight into your Grand Cherokee's performance

The Trinity T2 doubles as a monitoring powerhouse with a vivid 5-inch color touchscreen, swipe capability, customizable gauge layouts, real-time data display, and performance timers

For 2015 Grand Cherokee HEMI owners who want real horsepower gains, sharper drivability, and advanced tuning flexibility, the Trinity T2 Platinum + Unlocked PCM Kit is the ultimate upgrade
