I have been extremely happy with Dan Desio at Pro Dyno through the years. He's a stand up guy and really knows his stuff. They are in Fort Mill, SC right outside of Charlotte.
Take the ride down and see Dan at PRO Dyno he has tuned all my cars from my Ysi 331 Fox to my 03 f1 cobra and right now for Christmas he is running a special N/a tunes and S/C and turbo tunes for $350
