Turbo problems?

TxSpeedBoy · 01-05-2006, 04:42 AM

My car is fully stock and when I romp on it the boost goes to 6-7 psi. But I think I am missing the clowoff valve or the wastegate is broken or something, because the boost stays negitive unless I give it at least half throttle..goes to 0 at half throttle...goes to 4 psi at 3/4 throttle and 6-7 psi at full throttle. I also have nothing from the cat back because the previouse owner took it off. I think I am losing power as I know that these cars need back pressure...unless you are pushing 18+ psi. Is this reading normal or is it off...if so what could be some of the reasons?

-Thanks a bunch,
