Went to the dyno today
My buddy and i put 1 7/8 tsp headers on with x pipe b and b bullets and a airaid intake. Had it tuned today on a dynojet. How are the numbers considering i was using 91 octane fuel in canada here? (is there a differance in fuel quality?)
Tuner said with 93 octane,he could have got another 10 hp at the wheels. He put the tune more on the safe side.
Car is a 2007 c6 z06
