Gillette IMO never steered me wrong on info. And if you want some totally anal brainiac and dont mind paying 125 an hour go see DJ auto in Provo ALL ASE master techs and lead tech is an advanced diagnostics teacher for car quest. However RKL is a HACK. Ive got a few customers that went there and lemme tell you their KIDS are learning on your shit. 04 LB7 they pulled the customers recently replaced injectors from his wrecked truck and rammed them in dirty. He had shit smashed into his sealing washers, let the valve cover gasket fall into the head and cause a really nasty oil leak. valve cover bolts missing and loose. Same type of shit on other trucks from there Ive seen. It had bad balance rates ( I bet they let all kinds of shit in the injectors ) Broken wiring, Loose nuts on the GCPM. Dude strung me and my buddy along when I was working at ford wanting us to go work for him. we are both ASE master and hes Ford diesel master me just a LOT of furdd diesel and other certs as well as GM.
Your looking for a shop that's clean, organised, and full of name brand tools(not harbor freight) Has techs with age and experience not full of kids, certs on the wall and for gods sake transparency.
Unfortunately until I grow larger I cant keep on top of organised only make sure my products are 150% right :thumb:
