elijah Posted September 21, 2015 Report Share Posted September 21, 2015 I have a side mount whipple on my 2003, punched it today and noticed I only got 6 lbs of boost. What could be the possible problems? I have a 3 1/2 inch pulley if I'm not mistaken, shouldn't I be pushing more then that?? If anyone can chime in I would appreciate it.
