I purchased a new 2006 duramax and i cant seem to scan or read the tune off of it. It seems like efilive is not connecting to the pcm. Any suggestions?

EFI will not work with the '06 computers (LLY and LBZ) and from what they've said they will not support it. GM went to a Bosch computer system in '06 which is quite different than the Delphi system that was used before.
