The DiabloSport inTune i3 PCM Swap Kit is the ultimate tuning solution for 2015–2017 Dodge Charger and Challenger models with the 5.7L or 6.4L HEMI. These late-model muscle cars ship with locked factory PCMs that prevent traditional tuning, but with DiabloSport’s proven PCM Swap program, you can safely unlock your car’s potential and unleash real performance gains. This kit includes the powerful inTune i3 handheld tuner and a one-time unlocked PCM cross-shipment, giving you instant access to preloaded dyno-tested performance tunes designed specifically for your HEMI. On premium fuel, you’ll see gains of up to 25–30 rear-wheel horsepower, along with noticeable improvements in torque, throttle response, and drivability. The included transmission calibrations further refine the 8-speed automatic, delivering quicker, smoother, and more responsive shifting. The PCM swap process is simple. After receiving your inTune i3 device, you’ll complete a quick online cross-ship form to receive your unlocked PCM, along with a prepaid return label for your factory unit. Once installed, you’ll be ready to load tunes in minutes and feel the difference immediately. For Charger and Challenger HEMI owners, the inTune i3 PCM Swap Kit is the key to unlocking horsepower, torque, sharper throttle response, and enhanced shifting performance for a truly transformed driving experience.
