2019-2022 GM 1500 Gas Predator in-field

The DiabloSport 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.
