Hi, I bought my 2008 Duramax LBZ and it came with EFI LIVE on it, but no scanner or way to change the programming. And it is programmed in a way that is not economical for fuel consumption or towing capabilities, which is what I need it to do. Rather than buy the Scanner and attempt to mess with it myself, I would like some advice as to who to send it to that can change the programming so that I can adjust it as needed with a switch controller instead? Or remove the EFI LIVE loads and I will go back to Stock in the truck. I live in Upper Michigan and we don't have any diesel performance shops anywhere near me. I would most likely have to pull the ECM and send it out? Any help is appreciated. This is my first Duramax, I was a Cummins before.
