The DiabloSport Trinity T2 Platinum + Unlocked PCM Kit is the most advanced performance tuning and monitoring solution for the 2021 Ram 1500 5.7L HEMI. These trucks ship with locked factory PCMs that block tuning, but this package includes a DiabloSport Modified PCM and the powerful Trinity T2 Platinum handheld programmer, giving you everything you need to unlock your Ram’s true potential.
With dyno-tested calibrations preloaded, the Trinity T2 Platinum delivers up to 30 rear-wheel horsepower gains, improved torque, sharper throttle response, and refined 8-speed transmission behavior for quicker, smoother acceleration. The kit also enables MDS (Multi-Displacement System) disable, letting you keep your HEMI in full V8 mode for maximum performance and sound. Perfect for daily driving, hauling, or towing, these improvements give your Ram more strength and responsiveness in every condition.
For enthusiasts adding bolt-ons or advanced upgrades, the Platinum T2 supports CMR custom tuning, connecting you with DiabloSport’s nationwide network of tuners for dyno-proven calibrations tailored to your build. With built-in data logging, diagnostics, and performance testing, you’ll have the tools to monitor and refine your setup as your truck evolves.
The Trinity T2 also serves as a high-end digital monitor, featuring a vibrant 5-inch full-color touchscreen, swipe functionality, customizable gauge layouts, real-time engine data, and performance timers.
For 2021 Ram 1500 5.7L owners seeking real horsepower gains, better drivability, and complete tuning flexibility, the Trinity T2 Platinum + Unlocked PCM Kit is the ultimate upgrade.
