2004 STI Cobb AP tune














































Got a 2004 STI on the rollers to check a a cob stage 2 map that a friend of the client sent him.
Made a few pulls, the car was a little rich at the high rpms on the stage2 map. So I adjusted a bit. Unfortunately the stock clutch for some reason started to slip on 4th gear at around 4k rpms so we really could not see what the car would do with a little more boost and a bit of timing. In any case made some decent gains from what he came in and here are the pics from the tune that day.
Came in making 253awhp, left making 268awhp/280wtq @ 17psi tapering to 15psi
