The DiabloSport inTune i3 + Unlocked PCM Kit is the complete tuning solution for the Ram TRX, Dodge Durango Hellcat, and Jeep Grand Cherokee Trackhawk. These supercharged HEMI platforms come from the factory with locked PCMs that block traditional tuning, but this kit provides everything you need to safely unlock and unleash their true performance. The package includes a DiabloSport Modified PCM and the powerful inTune i3 handheld programmer (PN 8345). With preloaded dyno-tested performance tunes, you can expect 30–35 rear-wheel horsepower gains, sharper throttle response, stronger torque, and refined transmission behavior for quicker, smoother shifting. The result is a vehicle that accelerates harder, drives more responsively, and delivers the thrill your HEMI was built for. For enthusiasts planning upgrades, the Platinum i3 also supports CMR custom tuning, giving you access to dyno-proven calibrations tailored to your specific modifications. Built-in data logging makes it easy to track and refine performance as your build evolves. ⚠️ Important Note: On 2021+ models, you must save your stock calibration with your tuning device before removing the factory PCM. Please follow the included instructions for a seamless install. For TRX, Durango Hellcat, and Trackhawk owners who want power you can feel, refined drivability, and future tuning flexibility, the inTune i3 + Unlocked PCM Kit is the ultimate upgrade.
