  1. I just purchased a 08 GT500. It has a Airraid cold air intake and exhaust that I know of?
    The boost gauge max is 15 and it pegs it under full throttle . I have searched to see evidence of
    of a pulley or any other mods. How do you make sure it is stock pulley and etc. How do you know if it has a tune for the bolt-on's. I know you had to have to have a tune for a atleast a cold air?
  2. Post some pictures. It sounds like an upper and lower pulley. There is also the possibility of it being a stegmeier blower. Is there a tensioner pulley next to the blower pulley?
