I just received a supercharger from Wegner about 3 weeks ago. There return on phone calls and emails are horrible. I purchased front drive, holley hp ecu and supercharger. I hate to bitch but when you spend a pile of money and they flat out ignore you. I will tell you that Ted Jannetty of Jannetty racing is a sharp guy. He does a lot of newer Camaros. He calls you back. Give them a call
