The DiabloSport Trinity T2 Platinum + Unlocked PCM Kit is the ultimate tuning and monitoring solution for the 2017 Jeep Grand Cherokee 5.7L and 6.4L HEMI. These SUVs come with locked factory PCMs that prevent tuning—but this kit includes a DiabloSport 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 DiabloSport’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 2017 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.
