. I think we will see tuning options by the Fall or late Summer.
BTW our 19 2500 is on order in D1 status. We tried to get 4.10s in it, but the system wouldn't let us select that option

, so 3.73s it is. We had a 12 model with 4.10s and loved the pulling power it had and worked great with 35 inch tires. 3.73 is perfect ratio for stock tires up to 35s though.
