The DiabloSport Trinity T2 Platinum + Unlocked PCM Kit is the most advanced tuning and monitoring solution for the 2016 Ram 2500 and 3500 trucks with the 6.4L HEMI. Factory PCMs prevent tuning on these heavy-duty trucks, but this package includes a DiabloSport Modified PCM and the Trinity T2 Platinum programmer, giving you everything you need to safely unlock your Ram’s hidden performance. With preloaded dyno-tested tunes, the Trinity T2 Platinum delivers up to 20–25 rear-wheel horsepower gains, stronger torque, quicker throttle response, and refined transmission calibrations for smoother, more confident shifting. These improvements give your Ram more pulling power, sharper drivability, and a noticeable edge whether towing, hauling, or daily driving. The T2 Platinum also supports CMR custom tuning, giving you access to DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to your upgrades. Built-in data logging, diagnostics, and performance testing ensure you can monitor and refine your setup as your build evolves. With its brilliant five-inch color touchscreen, swipe functionality, customizable gauge layouts, and real-time monitoring, the Trinity T2 Platinum doubles as both a tuner and advanced digital gauge cluster. For 2016 Ram 2500/3500 6.4L HEMI owners seeking horsepower gains, improved drivability, and professional-grade monitoring, the Trinity T2 Platinum + Unlocked PCM Kit is the ultimate upgrade.
