Thanks! The power mods are Protune, APS 3.5" turboback exhaust with MIL.SPEC race cat welded in, and ported stock header. The 3.5" exhaust is what I'm told is the major cause of the power gains. The high flow setup is generating a little bit of overboost which we're using to our advantage. I believe it tops out around 16psi. Not sure how that compares though, still learning this crazy STi stuff.
