Well I hear all different stories from when I was in college. I had a friend that droped a pulley size and blew it up, but then this chick I worked with droped to a 3.4 on a stock tune and it was fine. So i figured for now I could go with a 3.5 or 3.4 pulley on a stock tune. The pcm will figure out that theres more boost and add more air and fuel. Well you guys seem to know whats up, how about a tuned pcm, 3.4 pulley and a catback to start?
