Part Number: PKITHCHAR21-T2

The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the all-in-one tuning solution for the 2021 Dodge Charger Hellcat. From the factory, these supercharged HEMIs are locked down against performance tuning. This kit provides everything you need—an unlocked DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345)—to safely unleash your Hellcat’s true potential. Preloaded with dyno-tested performance calibrations, the inTune i3 Platinum delivers up to 30 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined 8-speed automatic transmission behavior for faster, smoother acceleration. These upgrades make your Charger more powerful and more responsive whether on the street or at the track. For enthusiasts who plan bolt-ons or advanced builds, the Platinum i3 also supports CMR custom tuning, giving you access to DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to your modifications. Built-in data logging and diagnostics let you track, monitor, and fine-tune your Charger’s performance with precision. ⚠️ Important Note: On 2021+ models, you must save your stock calibration with your tuning device before removing the factory PCM. Instructions are included to guide you through the process. For 2021 Charger Hellcat owners who want real horsepower gains, quicker acceleration, and advanced tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate performance upgrade.
