[QUOTE="Justin@VMP, post: 10126738, member: 18468"] With the stock roush airbox and 90mm pulley they make about 6-7psi, that is what we always had until BG when i installed an 85mm pulley which didn't really make any more peak boost due to the restrictive enclosed airbox, just more low end. When you swap to an open airbox it makes a lot more boost. I love the roush kit, roush engineered a really nice belt system, the TVS makes great HP and TQ, and the kit is very reasonable priced. I have kits in stock and sell them for $6499 with tune. [/QUOTE]
