I recently installed a new clutch, which I have done numerous times before and ever since, my car won't boost pass 11psi. I had it it set at 15-16psi previously. I double checked and readjusted everything I could possibly think of but it did not help. I don't think this is a boost leak but I may be wrong. So this morning I decided to disconnect the nipple coming from turbo to the actuator to see if boost will creep since the actuator is now disconnected. And still I will only boost to 11psi! So now I'm thinking maybe the wastegate is stuck open? or it this a boost leak? Car boost fine to 11psi with no signs of leak or hesitations. It just wont go pass 11psi regardless of weather I turn boost controller up or down. Any thoughts would be appreciated. I also installed new plugs, wires, dist cap & rotor hoping to solve this but it didn't make any difference.

if you disconnected the actuator, did you cap off the line to the compressor? if you didnt then you would have a huge boost leak. if you did and still only got 11PSI with no wastegate, your turbo is toast.
what you did is very dangerous. no wastegate will allow the turbo to spool until it cant make anymore which is well in the 30psi range. you could have blown your engine. somethign is definatly wrong if you pulled that line and still only got 11psi. -------------------- 2001 Celica GT-S Turbo
