heres the story...bought this truck already with the dpf deleted so never had the module to take out the dpf delete program. My ecm messed up got it fixed and reprogrammed to my vin. thinking about doing the delete again because the dpf filter aint worth the fck and is already getting clogged. I was looking at efi live thats the only programmer that looks at a resonable price and not to interested in the smarty. if anyone has information on it and can explain it to me because I see a bunch of stuff such as V2 etc. someone please break it down for me. Thanks guys
