Not many in Cali there are a few down here I would say talk to Randy at Tunewerkes he is in Cali but I believe he does all his tuning remotely . You really don ‘t need a in person tuner with our cars. For stock Turbo tunes are not to crazy as they are limited to how much you can extract . All the tunes for stock turbo through tuners on the net work pretty well . If you are upgrading your turbo again tuners on the net have the turbo options pretty nailed. I originally went with a local shop here in SocCal for my S280 tune and well about a month or so later . I ditched it for a Tune+ tune over the net and never looked back . Car ran better with no codes unlike initial tuner. So ya sometimes in person does not always mean better with these cars.
