Those that have tuned or programmed
My Smarty programmer has economy, tow and performance settings. My question is, do you all tow exclusively in tow mode or any of the other 2?

Is EGR/EGR cooling still much of a factor now that the NOx is being controlled with DEF? (EGR is used much less and the fact that it lowers combustion temperature should offset, to some degree, the taxing of the cooling system caused by the EGR cooler) Any idea how the surface area of the radiators on the new Fords compare to the surface area of the air to air and radiator on the Ram? Does the current Ram use the same cooling system that they used on the 385 hp/865 lbft engine. It would be interesting to know how many btu/min these pick up truck cooling systems can dissipate vs the cooling system on something like a class 8 highway tractor.
