I have a 2.85 sc pulley ready to go on but Seb is a little hesitant to tune with it due to possible knock with the higher boost it will produce and running 91 octane.
Also, I highly recommend getting Tbatt's belt tensioner kit. I have no belt slippage at all. Seb was so impressed with it that he emailed me to find out where I got it, he wanted to order one for himself.
