I own an '05 C6 Z51 coupe and have been considering having Callaway install the supercharger performance package. I have been on the phone with Peter Callaway numerous times and have found him to be very helpful. However, since I am new to the performance game and have no experience with Callaway, what issues should I be concerned about before I move ahead? Have any of you had warranty disputes with either GM or Callaway after installing a performance package? If so, how were they resolved? How has overall reliability of the roots style supercharger been? How is Callaway post-sale support? Does gas mileage drop much with normal driving? Does the supercharger generate under-hood heat that the C6 cooling system can't handle? What advice do any of you have? ;help
