[QUOTE="BrianH87, post: 14533566, member: 159837"] I don't know if there a big difference in boost between a 90 and 85 pulley, but I would start with a VMP tune. An easy 50 hp gain. All I'm running is the phase 1 kit and a VMP tune. My kit is the newer one with an 85 instead of the old 90. Even with only a tune you'll be happy for a while. [/QUOTE]
