1999 Chevy Corvette

421 rear-wheel horsepower-that's a gain of 71 horses at the wheels! A not-too-shabby increase of 39 lb-ft of torque was also observed. After about five or six pulls, A&A had the air/fuel ratio pegged at 12.7:1 and the timing at 29 degrees, though with a little retard the LS1 was actually seeing 26 to 27 degrees.
