The DiabloSport inTune i3 PCM Swap Kit is the perfect tuning solution for 2015–2017 Ram 1500 trucks with the 5.7L HEMI engine. From the factory, these models are equipped with locked PCMs that prevent standard tuning, but DiabloSport’s PCM Swap program provides everything you need to safely unlock your Ram’s hidden power. This kit includes the inTune i3 handheld tuner along with a one-time unlocked PCM cross-shipment, giving you immediate access to dyno-tested performance tunes engineered specifically for your Ram 1500. With premium fuel, you can expect gains of up to 25–30 rear-wheel horsepower, stronger torque delivery, and a dramatic improvement in throttle response. Transmission calibration further refines shifting performance, creating a more responsive and enjoyable driving experience. The PCM swap process is simple and straightforward. Once your inTune i3 arrives, you’ll complete a quick online cross-ship form to receive your unlocked PCM, along with a prepaid return label for your stock unit. After installation, you’ll be ready to load tunes and feel the difference in minutes. For Ram owners looking for reliable horsepower gains, sharper response, and smoother shifting, the inTune i3 PCM Swap Kit delivers real-world performance improvements you can feel every time you drive.
