cool well when i did the conversion i already had the 2" so i wouldnt know how it would feel for a stocker..
i start to feel power from 3K and more when tvis kicks in is it just me or is tvis like a mini turbo effect.. once it hits.. its just goes pretty well and is awesome if your running pulp (tried 98Ron with octaneboost +3p and it felt really responsive) ive seen other 4AGE's from behind (just whatching =p) and you can really see that thing kick in.. its like the cars moving and the motion is like someone flicking it hehe
