The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning upgrade for the 2017 Dodge Challenger 5.7L and 6.4L HEMI. From the factory, these muscle cars are equipped with locked PCMs that prevent tuning—but this package includes everything you need: a DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345), giving you the tools to safely unlock your HEMI’s performance.
Preloaded with dyno-tested performance tunes, the inTune i3 Platinum delivers 20–25 rear-wheel horsepower gains, stronger torque, and sharper throttle response. Transmission calibrations improve shift speed and smoothness, giving you faster, more confident acceleration. This kit also enables MDS (Multi-Displacement System) disable, letting you keep your HEMI in full V8 mode for maximum performance and sound.
For enthusiasts adding bolt-ons or advanced modifications, the Platinum i3 supports CMR custom tuning, connecting you to DiabloSport’s nationwide tuner network for dyno-proven, custom-calibrated tunes tailored to your build. With built-in data logging and diagnostics, you’ll have the ability to track, monitor, and refine performance as your Challenger evolves.
For 2017 Dodge Challenger 5.7L & 6.4L HEMI owners who want real horsepower gains, sharper drivability, MDS disable, and custom tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate performance upgrade.
