The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete performance tuning package for the 2016-2017 Dodge Challenger Hellcat. Factory PCMs prevent traditional tuning, but this kit includes everything you need—an unlocked DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345)—to safely unleash your Hellcat’s full potential. Preloaded with dyno-tested performance calibrations, the inTune i3 Platinum delivers up to 30 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined 8-speed transmission behavior for quicker, smoother shifts. The result is a Hellcat that accelerates harder, responds faster, and drives more aggressively both on the street and at the track. For enthusiasts who plan bolt-ons or advanced performance upgrades, the Platinum i3 also supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners for dyno-proven calibrations built around your setup. With built-in data logging and diagnostic tools, you’ll be able to monitor and refine your car’s performance as your build evolves. This kit includes the inTune i3 Platinum programmer and a DiabloSport Modified PCM, shipped via a one-time cross-shipment to make installation simple while keeping your stock PCM safe. For 2016-2017 Challenger Hellcat owners who want real horsepower gains, sharper drivability, and tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate upgrade.
