I have a 2011 GT. It has Steeda pulleys, springs and CAI. Borla exhaust, JOT oil sep, and a high performance tune. I was wondering if the procharger or Whipple would be better. I kinda liked the way the pro fit in the car but I know very little about super/turbo charging. Please let me known what you think and if there is any maintenance type things associated with them.
