Will this STOP my engine from shifting between 4cyl and 8cyl?   2008 GMC Sierra 1500 5.3 V-8Russell J.Jan 27, 2021
Best Answer:Hi Russell, This part is compatible with the 2008 GMC Sierra 1500 GAS (Not Legal For Sale Or Use In California). No, this part would still allow the same functions the vehicle has. Superchips optimizes performance, will provide up to 114.4 horsepower and up to 162.5 feet pounds of torque for applications through custom engine calibrations to fine-tune overall engine performance and efficiency.
