The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the ultimate tuning solution for the 2018 Dodge Challenger SRT Demon, one of the most legendary limited-edition muscle cars ever built. From the factory, the Demon’s PCM is locked to prevent tuning, but this kit provides everything you need—an unlocked DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345)—to safely unleash its full potential. Preloaded with dyno-tested performance calibrations, the inTune i3 Platinum delivers significant rear-wheel horsepower and torque gains, quicker throttle response, and refined 8-speed transmission performance for faster, smoother shifts. These improvements push the Demon’s already insane acceleration even further, making it more responsive and powerful whether on the strip or the street. For Demon owners adding bolt-ons or chasing every ounce of performance, the Platinum i3 supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners for dyno-proven calibrations tailored to your build. With built-in data logging and diagnostic tools, you’ll always have complete visibility into your engine’s performance. This kit includes the inTune i3 Platinum programmer and a DiabloSport Modified PCM, shipped via a simple cross-shipment process that keeps your stock PCM safe. For 2018 Dodge Demon owners who demand the most from their supercharged HEMI, the inTune i3 Platinum + Unlocked PCM Kit is the key to unlocking unrivaled performance.
