I went to the track last weekend for the first time and I could only get 15 psi from the turbo?!? I got the WG for free, and the peice that connects to the turbo, the one that moves left to right, will only go right to a certain point until it gets stuck. That certain point=15 psi. I didnt install it either, is there something that has to be done when installing the wastegate in order to get >15? Please help as I had 0 knock on 92 octane!
