Re: SS S/C pulleys
2.8 will max you out at around 14.5 or so. It does this because the SC bypass valve is controlled by the pcm to bleed off any more than 14.5 pounds of boost. If you get the psi-fi kit it comes with a piggy back system that adjusts the perameters and you get around 16 pounds or so with a 2.8 pulley. It also comes with a belt tensioner pulley thats a bit bigger so you don't have to change the belt. The kit is around $550.
www.revitupmotorsports.net sells the kit.
