Want to tune my C7. Any good tuners in the OC? Or, should I just make the drive to Cunningham? Thanks!

No, there aren't. Lived in south OC for a decade up until recently. Only two places ever touched my C5Z and my C6Z....and that's Ryne at CMS, and Kohle at AHP. Both are worth the drive.

Steve at Powertrain dynamics in Huntington Beach....great tuner that works on everything, especially ls or lt vehicles. Just got mine done several weeks ago...doesent promote much, that's why don't hear much from him. Atleast not anymore. It's a one man tuning shop and that's how he likes it. Yet he's still busy tuning everything and anything. He did a great job with my c5. I've been going with him for over 10 years

Kohle and ryne are great but their not the only great tuners around, atleast what I've experienced with Powertrain dynamics.
