I just recently bought a 2010 WRX. It has some work already done on it, but I don't know exactly what all is done besides the obvious that I can see. Spearco TMIC, GrimmSpeed boost control, GrimmSpeed AOS, Turboxs turbo-back exhaust, AVO intake. The boost seems to go to about 20 psi. I'd like to find a nearby Subaru dyno/tuner to see what it's running now, and if it can be improved upon, I'd be more comfortable if the boost was about 18 psi. Then hopefully the shop can better judge what's done to the car so I can make future plans. I'm in Springfield, MO.
