Yes I had to take my truck there for some work. I was having a constant mis. I replaced the whole fuel system myself and Damn near the whole ignition system and still had the misfire with no codes or engine light. So I took it there they flashed the pcm and as soon as they did I got a check eng light. Read the code for me and ended up being coil number one. Very nice and helpful guys.
