I had a hard time finding a reliable GM performance shop around Southern California for my 2007 C6Z. After some research and phone calls, everyone pointed to Cunningham motorsports. I took my car there and everyone there was very friendly, knowledgeable, and honest. Had some work done to my car and my C6Z came out of there a completely different car. My car is a monster now! Going back there for E85 conversion and more! I would highly recommend this shop to all my friends and family!
