[QUOTE="decipha, post: 16290460, member: 74327"] 20psi is fine I've done several of them with no issues. It has to have a tune on it since the gt500s have a max load limiter table. If that hasn't been adjusted in the tune then it would make stock boost no matter what pulley you put on it. It would be best to find a tuner that can read the tune out and evaluate it rather than paying for a re-tune. Did the car come from the new orleans area by any chance? We do quite a bit of shelbys at my shop here. [/QUOTE]
