Description

The DiabloSport Unlocked PCM is required to unlock tuning capability for 2021 Dodge Charger models equipped with the 5.7L or 6.4L HEMI engines. From the factory, these cars are equipped with locked PCMs that block aftermarket tuning, but this modified unit provides the foundation needed to load performance tunes and unleash the true power of your HEMI.

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.
