boost issues

i had an issue like that with my old setup.

take the O2 housing off, and make sure the wastegate flapper is closing all the way. if its not closing all the way, bend the actuator arm a little to put more tension on it.
:tup:

if thats not the issue, check for cracks, or a bunk gasket between the turbo and manifold.

Yeah, and check when you have the o2 housing off, somtimes the casting around the wastegate hole in the exhaust housing cracks and erodes quite a bit, and its pretty common too.
