I got mine installed at Car Doctor. Either place Car doctor or Ultimate are good places to get your supercharger installed. Charlie insted the supercharger and dyno it at Ultimate, because the Car doctor don't have a dyno machine. Ultimate does allot of custom fabrications, see Chuck if you chose Ultimate Performance. I am very happy with Charlie work.
