Compatible with 2021 Dodge Charger Hellcat - 6.2L V8

Part Number: PKITHCHAR21-I3

The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete performance upgrade for the 2021 Dodge Charger Hellcat. From the factory, these high-performance models are locked down against tuning—but this package provides everything you need to safely unleash your Hellcat’s true potential. This kit includes a DiabloSport Modified PCM and the powerful inTune i3 Platinum handheld programmer (PN 8345). Preloaded with dyno-proven calibrations, the i3 Platinum delivers up to 30 rear-wheel horsepower gains, improved torque, sharper throttle response, and refined 8-speed transmission behavior for smoother, faster shifts. The result is a Charger that accelerates harder, responds quicker, and delivers a sharper driving experience both on the street and at the track. The Platinum i3 also supports CMR custom tuning, connecting you with DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to your bolt-ons or advanced modifications. Built-in data logging and diagnostics make it easy to monitor and fine-tune your Hellcat’s performance as your build evolves. ⚠️ Important Note: On 2021+ vehicles, you must save your stock calibration with your tuning device before removing the factory PCM. Instructions are included to guide you through a smooth install. For 2021 Charger Hellcat owners who want serious horsepower gains, sharper drivability, and full tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the proven upgrade.
