inTune i3 with Modified PCM

Description

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.

DiabloSport is a performance tuning brand known for developing high-performance calibrations for gas-powered trucks and modern muscle cars. Founded in the early 2000s, DiabloSport built its reputation on pushing the limits of factory engine management systems through advanced ECM and TCM tuning. As vehicle electronics became more sophisticated, DiabloSport focused on extracting maximum performance by optimizing fuel curves, ignition timing, throttle mapping, variable cam timing, and transmission behavior. The brand became especially prominent in the modern muscle car segment, delivering proven gains for platforms such as late-model GM, Ford, and Dodge performance vehicles, while also supporting gas trucks requiring improved torque, drivability, and towing response. DiabloSport products are engineered for enthusiasts seeking aggressive yet reliable performance gains and are designed to support bolt-on modifications and performance upgrades.
