no. i never used the superchip tuning. becasue of the heads and cam the tuning wouldn't work. i have ls1 edit and a guy out here that is sick at my tuning ls1's. Blown my air/fuel ratio was rich before i did the pulley, so we figure that with the 93 octane and having it already be rich i should be all set

 

Sounds good too me! Enjoy it!
