Compatible with 2021 Dodge Challenger Hellcat and Redeye - 6.2L V8

Part Number: PKITHCHAL21-I3

The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning solution for the 2021 Dodge Challenger Hellcat and Hellcat Redeye 6.2L Supercharged HEMI. These factory PCMs are locked to prevent aftermarket tuning, but this package provides everything you need—an unlocked DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345)—to safely unleash your Challenger’s full performance. With preloaded dyno-tested performance calibrations, the inTune i3 Platinum delivers up to 30 rear-wheel horsepower gains on the standard Hellcat and an incredible 54 rear-wheel horsepower gains on the Redeye. Along with the added power, you’ll enjoy sharper throttle response, improved torque, and refined 8-speed transmission performance for quicker, smoother acceleration. The Platinum i3 also supports CMR custom tuning, giving you access to DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to your bolt-ons or advanced modifications. With built-in data logging and diagnostics, you can track, monitor, and refine your Challenger’s 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. Instructions are included to ensure a smooth installation. For 2021 Challenger Hellcat and Redeye owners who want serious horsepower gains, refined drivability, and full tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate performance upgrade.
