Moved this topic from the general area.
I called Los Gatos Hummer and asked about it. The service manager said that it could be true but I have to be exact on which "updated programming" I am talking about.
So, does anyone know which "updated programming" I have to ask for? I found this info from Factory code download

04 Black Acura TL full A-Spec
88 Red Porsche rare 930 Cab
