The pulley is what increases the boost. The smaller you go the more boost you make. The stock pulley is a 3.8 and then they go down from there. 3.6, 3.4 etc.. The pulley's are about $100. A lot of tuners will have the pulleys at thier facility and will change the pulley to get you to the #'s you want to be at. I highly recomend getting it Dyno tuned. The Maggie tune leaves alot of hp on the table.
