From the bay area, these are the closest/best Duramax Mech's I could find

I like these guys, arrived early in the morning from the bay area and watched the shop open up. As the morning moved on, a bunch of Duramax's pulled into the parking lot and the guys opened up the shop. They look like they use all of the stuff they sell and can comment on their experiences and performance of the parts. They gave updates on the progress of the parts I got installed: Edge CTS 2, EGT Probe, Air Dog II 4G, Transgo Jr, tie rod sleeves and shim kit. I think I found my new Dmax mech's.
