The result is a Charger that drives with more confidence, both on the street and at the track. For enthusiasts looking to add bolt-ons or pursue advanced performance upgrades, the Platinum i3 also supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners for dyno-proven, vehicle-specific calibrations. With built-in data logging and diagnostics, you can track, monitor, and refine your Charger’s performance as your build evolves. ⚠️ Important Note: On 2019+ models, you must save your stock calibration with your tuning device before removing the factory PCM. Instructions are included for a seamless installation.
