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?

I tow mine in level 3 of 4 which is about 475 hp at the wheels. I never have a problem with EGTs, but my intake and intercooler is not stock. Neither is my turbo, exhaust manifold, and the rest of the 5" exhaust.
Most tune files aren't necessary tow and non-tow. They are labeled that because stock trucks can only handle so much before temps get hot. Hence the reason why even today's stock trucks with high power numbers defuel when the temps get hot. One can reliably tow on higher power level tunes if they have the mods to support it.
I realize the aftermarket is putting out some high quality components these days even though I haven't had any exposure to diesel engine mods. Anyway, I can understand how something like an aftermarket turbo can be easily designed to support more short bursts of horsepower and or a different torque curve but what is the aftermarket doing to get more cooling out of an intercooler? There is only so much air coming through the grill. If the engine is producing more power/heat and the intercooler is putting more heat into the air flowing through the coolant radiator, does the engine get hot pretty quick if you actually try using that additional horsepower on something like a long steep grade?
