I have the latest HPtuner version. I want to know if it will read and program the 08 Denali? It is a friend of mine and he had the dealer program it with LS1 Edit. The say they locked it. He is very tired of sending the VCM back and forth threw the mail and is wanting to know if HP Tuners will work on his truck. Also if it will and I can not get into it because they locked it can I get it unlocked some how? The LS1Edit programmer will not unlock it or at least thats what the programer says. Thanks all.
