just got off the phone with CAPA and he told me to go the 2.7 size pulley, so it's ordered and hopefully on it's way shortly. Considering I don't rev the crap out of the car or anything I doubt I'll have any dramas. He assures me the fuel setup they gave me and that can handle it fine. I' dunno what boost it'll be making though. The current 6 psi pulley only just makes 5 psi pretty much right on redline.
