Hey everyone, brand new to the forum and new owner of an '07 LBZ. I know alot about diesel and have always been passionate about then even though this is my first one. Anyways I was wondering how many of you have ran into problems with dealerships when you have your tuner and you bring it in for warranty work? Do you just take it out and set it back to stock they dont say anything or what? I am definately putting my bully dog on soon and getting my crazy larry downloaded after i get my transmission done and was wondering about any worries anybody might have. Appreciate it.
