Hello, everyone Im new to the site and new to EFIlive. I have an '01 duramax with the LB7 engine. I bought the tuner because I was curious about changing parametes in the trucks ECM. Does anyone have a good source for downloading tunes for this engine? I have found one but it is not reconmended for the stock transmission so i've been looking at it next to my stock program and editing it accordinly, any help is appreciated!
