Stock Boost Preasure
from searching I'm seeing on the 01 models the stock boost should be around 10-12 psi.
I installed the AWE boost gauge on Saturday the 6th and after installation I went out to test it, and it looked like under boost i was around -20 and boosting I would hit 13-15 psi, but since yesterday I'm only hitting 5 psi. does this sound normal at all? maybe like a break in period?

5psi on a stock turbo is the wastegate limit. This means the N75 isn't controlling boost (it isn't keeping the wastegate closed). Usually we call this "limp mode", and in most cases it comes with a CEL (check engine light). If you don't have a CEL, see if you can scan your ECU for fault codes to find out why you're in limp mode.

OK, yesterday after work I hit the auto part store to get my CEL checked out and I got three codes. P0442, P0455, and P0171. I knew i had a small evap leak from before and a lot of people were saying it could be the gas cap so I got that, installed it, went home and cleared the codes. after driving 20 minutes last night my CEL came on so I hooked the laptop up to the car today and this is what I got. 1 code less.
