Okay I need a little wisdom here please. When i bought my car it had a Boost controller on the car. Causing it to throw codes and over boost. I assumed it was an easy fix, so i took the boost controller off and replaced it with a vacuum line that fit snugly in it's place.
Well today I got around to using my COBB AP, which I have a stage 2 tune installed. Car has a catless turbo back, and HKS intake. When I installed the tune I figured it was running pretty good. So today I figured I had some time I was gonna take a quick data log. I tried to figure out how exactly to do it, I ran a real time boost guage on the AP. Looks like my boost from 3-7k rpm is in the 7's PSI, with a maximum recorded boost of 9.2 PSI. The car runs and feels pretty dang good otherwise.
So what I'm thinking is i don't have the right size vacuum line inbetween the turbo and wastegate where the boost controller was, or if it is the right size, i need a restrictor pill.
