So I bought a 2011 a few months ago. It has had all the dealership updates done to it for the AFM issue. Costing the previous owner a lot, GM shared the cost of the mistake. I don't like the shift points of the stock programming and I am going to disable the AFM and add a custom tune.
 
(y) Nice! Fantastic tool. Got a DiabloSport years back to disable the AFM.
 
Diablosport 87 tune absolutely 'fixes' the shift pattern! So much better to drive, and closer to the 4-speed feel I was used to.
