Basically, this CCM update reduces or eliminates eLSD rear bias.
I've been trying for several months to find a Denver area dealer to do this with no luck. No one knows anything about it. You would think GM could provide this with little effort but not so.
Does anyone know of a dealer anywhere that knows this update?
