When we tuned the car, we had to taper boost to like 12psi by redline because there wasn't enough injector left. (stock WRX injectors are weak shit) So, with the car being at like 3800rpm at the start of the pull, being in 3rd gear, and injector limited, I seen 18 psi (max is 19psi on the street) for just a split second before the boost tapered to like 12 psi for the rest of the run.
That being said, I seen a gain of 3 WHP and 21 WTQ from $200 worth of mods (Ebay downpipe, used Grimmspeed EBCS) with the most recent dyno runs being about 30* warmer than the baseline.

Here is what I was talking about with my boost and RPM's:
On the street it will hold at 18ish for at least a couple thousand RPM's, where here, it just instantly died off. Maybe I should try a 2nd gear pull some time, just to see what the boost does without so much load on the car.
