2020 GMC Sierra
Supercharger: P-1SC-1
"500HP 5.3L!"
Modifications and Additional Specs:
Stock and ready to rock thanks to boost! These new trucks and their 10 speed transmissions were BUILT for the centrifugal supercharger boost curve, or so it seems. Bolt on loads more HP and TQ, and be ready to play, pass or pull with ease!
