Description
Overview
The DiabloSport Predator 2 7226-R Kit is the complete tuning solution for 2019–2022 (pre-refresh) Chevrolet and GMC trucks powered by the 5.3L and 6.2L gasoline engines. From the factory, these trucks are locked down, making traditional tuning impossible—the Predator 2 kit changes that. Bundled with the Predator 2 handheld programmer plus the locksmith device and harnesses required to unlock both the ECM and TCM, this computer chip programmer gives you full access to engine and transmission tuning on platforms that were previously off-limits.
Instead of settling for the conservative calibrations GM ships from the factory, you gain the ability to reprogram how your 5.3L or 6.2L truck runs, then fine-tune the driving experience to match how you actually use it—daily driving, towing, or all-out performance.
Key Benefits
This kit is built around real, usable functionality. A color display makes navigating menus, selecting tunes, and monitoring your engine straightforward. Built-in performance tunes let you unlock more from the 5.3L and 6.2L gas engines, while data logging helps you and your tuner track exactly what the vehicle is doing under load. The included speedometer correction feature keeps your readings accurate after modifications, and the engine service capability adds diagnostic-focused value beyond raw power.
Custom Tuning & ECM/TCM Unlocking
The headline advantage is access. Because the kit includes the locksmith device and harnesses needed to unlock both the ECM and TCM, you get full engine and transmission tuning control rather than engine-only adjustments. The Predator 2 supports custom tuning and accepts custom tunes from CMR, so you can load calibrations dialed in for your specific truck and goals. That combination—factory-locked hardware opened up, plus custom tune compatibility—is what makes this a genuinely complete tuning package.
