The Diablo Sport Predator 2 7226-R Kit is the complete tuning solution for 2019-2022 (pre refresh) GM trucks powered by the 5.3L/6.2L gas engines
From the factory, these trucks are locked down, making tuning impossible-until now.
This kit includes the Predator 2 handheld programmer, plus the locksmith device and harnesses required to unlock both the ECM and TCM, giving you full access to engine and transmission tuning.
Once unlocked, the Predator 2 delivers dyno-tested tunes designed to add noticeable horsepower, torque, and throttle response while improving overall drivability
It also offers dedicated transmission calibrations, letting you choose from multiple transmission tunes to refine shifting and power delivery to match your driving needs
For those who want even more, the Predator 2 supports custom tuning through Diablo Sport's nationwide network of CMR tuners, enabling dyno-calibrated files built around your truck's unique setup
Beyond the preloaded and custom tunes, you'll also have access to a wide range of user-adjustable parameters, including throttle response, speed limiter, tire size calibration, and DFM disable
New features for these models even include last mode recall and Auto Start/Stop retention
For GM truck owners who demand real-world performance gains and the flexibility of both preloaded and custom tuning, the Predator 2 7226-R Kit is the key to unleashing your 5.3/6.2 powered Silverado or Sierra
