Looks good Tony! I always salivated over the arctic white '06-07 STi
I ran about 20psi on my old '06 STi and netted around 300ish on the ASG hub dyno back in '07 (have to find thread)
You seem to have all the good supporting mods (ARC intake farken dont let go of that - like gold!!)
At the end of the day numbers mean feck all, get it out on the 'plex, barbs, collie to get the 'proper' numbers!
edit: found it
