The DiabloSport Trinity T2 Platinum Performance Kit (PKIT) is the most advanced tuning and monitoring solution available for the 2021 Dodge Charger 5.7L and 6.4L HEMI. From the factory, these models come with locked PCMs that prevent traditional tuning, but this package includes everything you need to safely unlock and transform your Charger’s performance. The kit provides a DiabloSport Modified PCM and the Trinity T2 Platinum handheld programmer, giving you access to preloaded dyno-tested tunes that deliver up to 25–30 RWHP gains, sharper throttle response, and refined 8-speed transmission behavior for quicker, smoother shifting. The result is a more powerful, more responsive Charger that performs better whether you’re daily driving or pushing it on the strip. The Trinity T2 Platinum also supports CMR custom tuning, allowing you to work with DiabloSport’s nationwide tuner network for dyno-calibrated files built for your bolt-ons and advanced upgrades. With built-in data logging, diagnostics, and performance testing, you’ll always know how your HEMI is running. Its sleek five-inch color touchscreen features full swipe functionality, customizable gauge layouts, and advanced monitoring for all your Charger’s vital data. For Charger HEMI owners ready to break past factory restrictions, the Trinity T2 Platinum PKIT is the all-in-one upgrade for horsepower, torque, throttle response, and custom tuning flexibility.
