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?

There is nothing wrong with advertising short burst power over sustained power. It is completely legit using SAE methods and all of them do it to a certain extent. Some more than others. To some companies, highest power ratings possible is more important for marketing and being "best in class". Other companies feel that sustained power is a more important figure for their customers. I have worked for both Ford and Cummins and I would definitely put Ford in the former while Cummins was more in the later.
Ford knows that "best in class" power ratings sells more trucks, and they will do whatever they can to keep these titles. So does Ram, and they(or Dodge at that time) wanted Cummins to post highest power levels possible back when I was there and probably still do. However, that is not the way Cummins does things and would rather give a more sustained hp rating to their customers rather than a short burst power rating so they tune their engines accordingly.
Take the Ford F450-550 and Ram 4500-5500 trucks. The highest rating for the PSD is 330 hp while the highest rating for the CTD is 360 hp. That alone tells you that the Cummins is able put out more sustained power since the emissions and power certifications on these trucks is geared towards the emissions and power at sustained power outputs.
