Yes, the Hypertech works with the 2011 - I'm running it on mine. It adjusts for tire size and also checks and clears DTCs. Was about $200 from Summit.does anyone make just a tire size adj that will work on the 11's? i would rather just have the tuner with it all built in but if its going to be another 2 years i'm not going to wait around. my speedo is off by 10 mph and its getting a bit old.
