Your wastegate should not be open at idle - I would make sure all your routing is good and go from there.

sounds like a leak in the charge piping. Also, like stated above, your WG should not open under vacuum. Make sure the top port isn't of the manifold side of the throttle.

found the wastegate leak, broke the mounting flange on install .. new one on the way .. took a long look around last night patched a few small exhaust leaks and things, I am now able to see about 5psi in 3rd and 4th .. so I feel alot better about it, now I need to get my injectors in and get a tune =]

Thanks for looking out guys

if your pcv system is stock, then you'd better change that as well. It wont be able to vent under boost. Glad you got the leak figurered out!

I have bigger problems now .. after driving around on very low boost (4psi) and maybe boosting about 10 times I got home and cut the car off and now it wonts start im thinking fuel pump went out I only see a max of 16psi at the rail while turning the car over. (new post going in the fueling section for more help) Thanks a lot im sure i'll drudge this back up when I get the w/g flange fixed. So do I just need to unplug the line going to the pcv and put a cap on the intake?

sounds like the hose to the pump came off or split....fuel pump is generally like a light bulb...it works or it dont.
