Are there any good shops around the Denver area that can rebuild my 2nd Gen. Supercharger? Or for that matter in the country? I called and left Magnuson several messages to call me that I needed my charger rebuilt but never got so much as a boo back from them. I got pissed and called the human resource dept. and got hooked up instantly. The guy on the phone was pissed and I could tell he was pissed. He told me the cost could be anywhere from $800 to $2500 dollars. So now I feel like I just sent my food back and the cooks going to spit in it. Are they the only ones who do rebuilds?
