So you guys dont think a 12 lb pulley will hold up and yeah i know about the whole A/F thing!!!! a whole new tune is in store if a 12 lb pully is a wise choise. Im making 10 lbs of boost right now, and around 359 rwhp. You dont think i could make 12 lbs safely then??? Also what would you run for MAF, ive got a 80mm maf pro m calibrated for 42lb injectors. Would you go with a 90 mm, ive heard that the lighting MAF works great, any feedback on that please thanks!!!! Jake
