Good MPG coming home this past weekend from PA (~29mpg), this just started happening this afternoon. car drives just like normal when i'm not in boost and just cruising. Once I step on it to start boosting, it starts jumping all around and freakin out.
I was thinking bad plugs, but if it was that... my idle and stuff should be crappy, no? Scott suggested it's possibly the N75 (do these go bad?).
