Available reprogramming from GM itself?

It seems that the reprogramming software and logging is available directly from gm..

that would be for authorized dealers only my friend. They can change a few settings at the dealer, ie speed governor for certain types of tires, performance axels etc.

That will be with a tech 2?

YOu could buy that...
