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?

Argument? I am just stating facts that even the new 475 crank hp Powerstroke is not a sustained power level and will defuel when temps get too hot. All diesel engine will do this to a certain extent. If you don't believe me, go ask a Ford engineer or the guys at Calibrated Power Solutions who made that tuned towing comparison video Fish posted a while back. Heck, they even state it in one of the videos in that series.
I am sorry if you can't handle the truth and think it is an argument. I would suggest to stop quoting me like you did in this thread if that is not something you want to hear. Truth is, some manufacturers post sustained power numbers and some post quick burst power numbers that cannot be sustained over long periods of time under heavy load.
Better yet, go buy an Edge CTS monitor and watch EGT, commanded fuel pressure, actual fuel pressure. You will see fuel pressure starts to drop (defuelinng) when EGTs get too high.
I know the Cat in my 07 Peterbilt will defuel when it gets too hot on a long hard pull. I suspect my Ford will defuel if ever gets too hot and I hope the Cummins will as well. I see that as a good thing. When TFL pulled 30,000 lbs up to the Eisenhower tunnel I wouldn’t call that a short burst of HP.
