Just installed my perrin tmic on a 07 sti. Everything seems to be fine but pulls In 1st and 2nd gear will hit about 2psi short of what my car usually boost at. 3rd gear and up it'll hit boost target fine. Also, I can hear a lil more air being wooshed around than usual. Can't really tell because of my cai. Is this normal for the car to be actin this way? I haven't got it tuned yet. Am I just being paranoid? Lol thanks In advanve

 

paranoid. It is fine. If the car feels like it just blew a motor that is a boost leak worth reporting


colder air = more dense
