I got my AP in today, installed it with just the OTSM for now until a real tune. I was happy to hear the whine of the turbo again from the downpipe. Not really any louder with the turboback. So over all happy, my first impression is 1st gear is useless ..2nd is there for a bit getting a bit better...then 3rd...WOW full boost pull.... some what like my STI did. That is all for now.
