Product Details

The Diablo Sport in Tune i3 PCM Swap Kit is the complete tuning solution for 2018 Ram 1500 trucks with the 5.7L HEMI and 2019-2024 Ram 1500 Classic 5.7L models

This kit includes the powerful in Tune i3 handheld tuner plus a one-time unlocked PCM cross-shipment Once installed, you'll have access to dyno-tested performance tunes engineered specifically for your Ram 1500On premium fuel, these calibrations can deliver gains of up to 30 rear-wheel horsepower along with improved torque, sharper throttle response, and smoother overall drivability

The swap process is simple After receiving your in Tune 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 With your new PCM installed, you'll be ready to load tunes in minutes and immediately feel the difference
