hey guys! i got this problem when i hit 8 psi i notice my fuel pressure will go from like 120 to 110. i have the missing link so i know it can't be that. my car also stutters a little bit at crusing speeds. it doesn't feel like it is getting full power either.my spark plugs are only 3 months old and i checked them and they seem fine. my car sit in the garage all week long untill the weekend. what kind of a/f ratio should i see at 8 psi of boost. mine will go in the low 13's when hitting full boost. at idle and crusing it is in the 14's.
