[QUOTE="fuelforfire87, post: 16677482, member: 172024"] Just had my car tuned by Lund with JLT 123 CAI, VMP twinjet 67, BPS oversized elbow, a 2.4" upper pulley and 90mm idler, on 93 pump gas. Asked whether or not before starting the tuning process if I would need a BAP. I was told no. After datalogging was told the fueling was on point. These cars have dual pumps so they are more than capable of supplying enough fuel on pump gas without a BAP. Stock pulley size is 2.7 so only a 2-3 psi increase over stock. [/QUOTE]
