I've had db do work on my 02 wrx, specifically fixing problems that another speed shop caused. They were very helpful, friendly, and understanding through this massive headache. Although the pricing ended up being more than I wanted it to be the work has been great and you get what you pay for. My biggest compliment has been that they take time to talk through things, answer emails with detail, and explain options. Something that I didn't receive from other shops and caused issues. The tuner really knows what he's doing and will set you up with a solid safe tune.
