So since getting a boost gauge on my 04 STi, I noticed between 8 - 9 psi was my max. low for even a stock STi. After checking all vacuum lines and the waste gate actuator I came up with nothing. I just got my Cobb AP and flashed to stage 1 figuring someone before me set the boost lower. but thats a no go, still getting 8.4 max. Didn't change at all. does anyone have any ideas as to how to fix this issue or what the root cause may be? I also have a data log from my AP if anyone could take a look at it and see a rhythm in the numbers.
