Product Details

The Diablo Sport Predator 2 7266-R Kit is the complete tuning solution for 2020-2023 GM trucks equipped with the 6.6L L8T gas engine From the factory, these trucks are locked down, but Diablo Sport provides everything you need to safely unlock and unleash their true performance.

This kit includes the Predator 2 handheld programmer, Diablo Sport's exclusive Locksmith device, and ECM harnesses-eliminating the need to remove your ECM Once unlocked, the Predator 2 gives you access to dyno-tested performance tunes that deliver up to 28 rear-wheel horsepower and 50 rear-wheel torque gains over stock

The result is stronger acceleration, more pulling power, and a truck that feels more responsive in every situation
