I have a .63 trim and it works great. I had a smaller turbo and once you start to hit high RPM's the turbo would die off because it "chops" the air and cant push the air fast enough. I dont think that is your problem though becuase before the turbo worked fine. I would have to agree with everyone else here. your leaking somewhere. Check your BOV.

ok guys i took your advise about the intercooler thing, well kinda your advice, i just took it off because it was already tight, and the guy damn thing is still doing it, but not as bad, instead of going down to 1PSI, it goes down to about 3 PSI, and also while i was taking it off i realized that my charge pipes where relly thin, they are probobly 1 inch inside, i literally bought all my charge pipe stuff from home depot, so that may have something to do with it, i need to but a reall front mount intercooler rather than my shitty saab one, and some actual metal pipes i have this plumbing pipe thing with metel wound around it so it doesnt collapse,what a peice of ----, but i also think the problem has something to do with the wastegate , on my next day off im gonna buy somemore vacuum hose and change the vacuum source for the wastegate.
