I was driving down 93 South the other day having fun with a CTS and S4 and that's when I knew I definately needed some more "omph." I know of a local GIAC dealer but it seems that APR is the way to go. I just don't know where good dealers are. I used the APR website to find a couple places but I want some first hand recommendations. I live right by the border btw MA and NH. Its a 1/2hr drive south to Boston and 1/2hr drive north to manchester, nh. Any advice would be much appreciated.Thanks guys.
