Try plugging the V2 into the laptop first then into the truck. I have found that when I plug the V2 into the truck first and then into the laptop it wont upload the tune.

Are you the original owner of the LB7? If not do you know if it has been tuned before? If no idea I suggest having a GM service dept flash the latest GM tune in with their GM Tech II or if you know one with a GM Tech II scanner to do that for you. EFILive cannot write over a locked ECM on the Delphi LB7 and LLY ECMs if this is the problem. search for the codes here in the search tool if you have not gotten it resolved yet.
