[QUOTE="LargeOrangeFont, post: 10832326, member: 22835"] You can always throw on a smaller upper too. Start with 3.1 and if you have the cooling headroom for more power drop pulley sizes and retune if needed. The throttle response is great on track with the accufab throttle body. It makes rev matching much easier. With the 3.1 you can run stock injectors, fuel pump and driver, and will be at about the limit of the MAF. If you go to the lower pulley, you will immidiately need a different/recalibrated MAF and corresponding tune. [/QUOTE]
