Compatible with 2015 Dodge Challenger - 5.7L/6.4L

Part Number: PKITCHALV815-I3

The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning package for the 2015 Dodge Challenger 5.7L and 6.4L HEMI. Factory PCMs block tuning, but this kit includes everything you need—an unlocked DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345)—to safely unlock your Challenger’s performance. Preloaded with dyno-proven performance calibrations, the inTune i3 Platinum delivers 25–30 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined 8-speed transmission behavior for faster, smoother acceleration. You’ll also be able to disable MDS (Multi-Displacement System), keeping your HEMI in full V8 mode for maximum power and sound. For enthusiasts looking to push further, the Platinum i3 supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners for dyno-proven calibrations tailored to your modifications. Built-in data logging and diagnostics provide the tools to monitor and fine-tune your car’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 to guide you through the process. For 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.
