John from Pennsylvania switched to Tapout after having unresolvable drivability problems with a competitor’s tune. Our technicians switched over his fuel cam to a properly engineered unit, installed a Gigs ported throttle body and Brisk Silver Racing spark plugs. Then we strapped the car to our DynoJet for a custom dyno tune. The results were a very impressive 632 whp and 669 wtq and a car that drives as smooth as OEM. Specializing in LF4 engines has allowed us to become the absolute best at what we do.
