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?

That sounds wonderful. If the Ram grill area is large enough to supply cooling for 475 sustained rear wheel HP we likely haven’t seen the end of the hp increases from the factory trucks.
You are forgetting about emissions again and how they play into the sustained performance and efficiency of a stock engine.
I could not sustain 475 hp at the wheels on stock turbo with emissions equipment.
Who said anything about leaving the turbo as is? Cummins can change whatever they need to.
I said stock turbo AND emissions equipment. You also cannot go too big on a stock turbo due to low rpm emissions even with a VGT. The high power numbers of today's trucks are not sustained for the most part. Like the 475 hp at the crank of the new PSD, it is not sustained and will defuel to a lower power as temps rise.
