who here has APR stage 2+?
I probable don't have to say I had it. No numbers from me but if I remember it was around 15 peak hp on the max but down through out all rpms you were getting more. I would call APR as could not find on the site. Well worth it
i have it. its noticeable. couldnt give you dyno numbers - i might get it dynoed in january. look into hpfpupgrade.com if you go stage 2+ you will want to upgrade the pressure relief valve.
