i think i messed something up, ok heres the scoop. I recently put a Autometer boost gauge in my car and also did the 3/16 restictor mod that was on the scoobymods website the car ran great, so i decided to try something else i removed the small t-valve that in between the turbo and the wastegate and put in a larger one a 3/16 the car ran better i was boosting at 15psi and i could really feel a noticable difference, it sucked you to the seat even more. So stupid me decided to take it off agian an put the smaller t-valve back on in fear that i would damage something and now my car seems like it has now boost at all, it sucks. SO i put the larger t-valve back in and still the same hardly no boost my gauge is only reaching 9psi to 10 psi max in all gears even a redline in all gears. I reset the ecu and still nothing has changed i need help. I miss my boost feeling. could the silenoid be bad. Also i checked for leaks and found none. Please enlightin me and tell me how to correct this problem somebody.
