Same here. 2015 ram 6.4 91 tune. Only option is Tire size and Traction control. No MDS no throttle boost and no transmission setting. Tire size and traction error out and say wont write. What gives?

This week is now a month later Poke poke.

Any update on 2015 6.4? When will this be available (Assume still a PCM swap right?)

I too am awaiting the 2015 Ram 2500 6.4. Have a power wagon version. When is the ETA?
