Where exactly are they located though? Are there two separate locations that serve different purposes? Heard they were in san jose, but is one of their locations in Sacramento?
I think you're right. Don't quote me on this, but they have an in-house dyno at their shop to do tuning in San Jose/Santa Clara and they share a dyno with another shop in their Sacramento branch, but have their own Sac garage. It's best to call to find out the details.
I still say nothing beats learing and doing the work yourself, but not all of us have the time to do so, which is why shops exist
