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?

Shiner I know you know some things. I also know you have more experience with tuned engines than I have, but when you say things like:
it comes across to me as though you are claiming that you can reliably put 475 HP to the pavement with a tuner plus a few mods to your intake and exhaust.... maybe you can for a 20 second run. Maybe you and I both know that, but you don't say it. You don't say that if you actually made your engine deliver 475 HP to the rear wheels the engine would overheat in a matter of minutes; You don't remind whoever is reading this that the 68rfe is designed to handle 300 rear wheel horsepower and that it will have a very limited life if it is expected to handle 475 HP. Whether the Cummins engine can tolerate that kind of power for any length of time or not I don't know but I suspect that if Ram ever wants to increases their power ratings to the 548 crankshaft HP you talk about, Cummins will make some significant changes to their 6.7 and not just because of the emission BS. I actually started out wanting to ask you some questions to learn what is out there in the aftermarket diesel world .... especially in the area of cooling.

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.
One can reliably tow on higher power level tunes if they have the mods to support it.
