Off to read the tuning bible again...
high speed 3.75 and low speed 3.75 , idle screw opened 1 full turn from just closed

very very close with most pipes

hope this helps

and the guy getting only 5 - 6 min. runtime , i can guarantee you with 100% accuracy that it is not your engine and you got something else going on in the car guarantee it or i'll eat my shorts
