I will check again for leaks, but I dont think there is any. I rebuilt the turbo a fews weeks ago from .63 down to .48, because the lag was really bad and 12 psi was all I could make. Now I can make 15ish about 4500-5000, but I built this engine for 300, and 245 is a little short of that. Is there a way I can bypass the wastegate to see for a second if it can boost higher than 15-16??
