For all intents and purposes, an 80HP tune is going to add a lot of fuel above stock and there is simply not enough air density to support that much fuel while towing.
I would suggest a lower HP towing tune.

Makes sense. I don't tow that much, so 80 daily had been planned as my primary - and the one I have been using. 80 Tow looks like a smoke show, only tried it once. What tune should I go with to maximize MPG - that is my end goal is maximizing MPG over stock, not looking for best performance.
