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?

We have a 2020 f250 6.7l diesel towing a 38’ tandem I only tow in tow mode.

I have a hydra tuner on mine which has 3 different tow tunes depending on the weight. I always use a tow tune. Tow tunes are made to keep your EGTs in check, a performance or eco tune may not do that.

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.

Most tune files aren't necessary tow and non-tow. They are labeled that because stock trucks can only handle so much before temps get hot. Hence the reason why even today's stock trucks with high power numbers defuel when the temps get hot. One can reliably tow on higher power level tunes if they have the mods to support it.

48RE is your issue for turning up the wick and towing heavy.
Unless it’s built, or you have a G56 with a good clutch.
I have had my 07 on a “200hp” tune, whatever that is, almost exclusively since new. Towing or not.
I drive by egt when pulling grades.

Never had to slow down due to lack of power grossing 20k combined and 12’ tall. (not a lot I know) only have to back out due to egts sometimes. Stock turbo doesn’t move quite enough air for that much fuel.

I realize the aftermarket is putting out some high quality components these days even though I haven't had any exposure to diesel engine mods. Anyway, I can understand how something like an aftermarket turbo can be easily designed to support more short bursts of horsepower and or a different torque curve but what is the aftermarket doing to get more cooling out of an intercooler? There is only so much air coming through the grill. If the engine is producing more power/heat and the intercooler is putting more heat into the air flowing through the coolant radiator, does the engine get hot pretty quick if you actually try using that additional horsepower on something like a long steep grade?

My turbo is not for short burst power. I specifically picked the it for sustained towing power, and it keeps temps down way better than the stock turbos from any of the brands. The intercooler is more of a supporting mod for the greater CFM of the new turbo. It was larger than the factory in thickness and mounted in the same spot under the radiator pulling air through the gap in the front bumper. I did notice about a 5-10% drop in intercooler temps and EGT's which I monitor on my Edge CTS2 than stock.

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.
