Good afternoon... new to this but wanted to find a good tuner in southern California?
I have many So Cal friends from Cobra & Shelby Club and racing against them. I shot a request to a friend of mine who was employed by Edelbrock and he managed their cars when we raced against Vic Edelbrock and the daughters Camee and Christi.
Mike came back with a great resource for you.

This looks like it is very close to you and they have a chassis dyno and an engine dyno.
If you have ever watched the TV show "Engine Masters", this is where this dyno TV show is held.
Ask for Steve Brule, he is a master at tuning. Tell him that Mike Eddy recommended that you talk to him.
Good luck and I hope this helps.
