The DiabloSport Trinity T2 Platinum + Unlocked PCM Kit is the most advanced tuning and monitoring package for the 2017 Dodge Challenger 5.7L and 6.4L HEMI. These cars are equipped with locked factory PCMs that block tuning, but this kit includes a DiabloSport Modified PCM and the powerful Trinity T2 Platinum programmer, giving you everything you need to safely unlock your Challenger’s hidden performance. Preloaded with dyno-tested calibrations, the T2 Platinum delivers up to 20–25 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined 8-speed transmission behavior for faster, smoother shifting. The result is a Challenger that accelerates harder, reacts quicker, and performs with the power you expect from a HEMI. For enthusiasts adding bolt-ons or planning advanced builds, the T2 Platinum supports CMR custom tuning, giving you access to DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to your setup. With built-in data logging, diagnostics, and performance testing, you can monitor and refine your car’s performance as your build evolves. The T2 also serves as a monitoring powerhouse with a crisp 5-inch full-color touchscreen, swipe functionality, customizable gauge layouts, real-time data display, and performance timers—all in one sleek, easy-to-use interface. For 2017 Challenger 5.7L & 6.4L HEMI owners who want real horsepower gains, sharper drivability, and tuning flexibility, the Trinity T2 Platinum + Unlocked PCM Kit is the ultimate upgrade.
