Built-in data logging and diagnostics provide the tools to monitor and fine-tune your car’s performance as your build evolves.\n⚠️ Important Note: On 2019 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.\nFor 2015 Challenger 5.7L & 6.4L HEMI owners who want real horsepower gains, MDS disable, and advanced tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the proven performance upgrade.
