EGR Valve

Nick,

Glad to hear that your experience at the dealer was a good one and your truck is running good now.

This is just my common sense talking, but I think most if not all cases where the customer gets grief for their mods via the techs when seeking warranty repairs comes down from the service department management directing them to report anything suspicious. Most of the dealer techs I have talked with are gearheads themselves and have a lot of the same mods done to their personal vehicles, and therefrore could care less what mods you have. The dealer probably got burned by GM in the past when they didn't get paid for a big warranty job or three because of mods they "overlooked" and got caught somehow.

the egr valve to the lbz is like the injectors to the lb7 and the #2#7 connectors to the lly. very common, no bs from gm on the replacement ect. in and out. that is why i said to leave it in there.
