I just purchased a 05 Yukon Denali and the door says it has a hypertech installed. Is there a way I can check to see if there is a chip or if it's programed with a hand held? It seems like with the lightest foot available it is only getting 12 I know that's not bad but I that's never going over 2k rpm and mostly 60 highway. I think it might be tuned for performance and not economy.
