The specialize in Subaru and Mazda - especially performance and race work. Great guys. They've helped me out a few times when the problem was beyond my ability diagnose (what I thought was a water issue they knew immediately was a cam angle sensor). The do tuning, and they have a dyno on sight. They are fellow enthusiasts, and plenty of interesting cars hanging around the shop.
