My Ride: Max PSI Stage 2
Usually the smaller the blower pulley you go, the bigger crank pulley you go. This is to prevent belt slippage and whatnot. Smaller blower pulley = more boost = more power. You will have to check with VFE to see if your injectors can handle the new pulley setup. And then you will need to be retuned of course.
