I have a Livewire TS tuner in my truck. It has 4 tunes. Street 1, Tow 1, Performance 1, Extreme 1 Which one is going to be best for fuel milage on the highway for a trip. I will not be pulling anything. I am in Tow now since i have been pulling my camper at 13.3 and am averaging 15.3 not pulling anything. What is the opion of you Diesel experts?

The higher hp tune, the better the mileage for the most part. With that being said, I wouldn’t suggest running the hottest tune if you are going to be towing much at all.
I’ve got a 2019 6.7 tuned with an EZlynk, and it never comes off the 45hp tow tune. It’ll get better mpg and is more fun to drive on the hotter tunes, but I tow quite a bit and don’t want to risk tearing anything up.

I am always in tune #3. 550 HP and 1200 ft lbs. Same truck as you. It's the appropriate amount of power to pass people quickly and efficiently. FWIW, I have 175k miles on the clock, I am still on the factory transmission, and had it tuned at 40k miles. Just don't rag on it, and it will last forever.
I have no idea what I get for fuel mileage. More than 12. It's a 3/4 ton, it gets what it gets LOL

Your livewire has "canned" tunes. On the powerstroke I only use Ezlynk with custom tunes as they run and shift smoother and do seem to get better fuel milage. Like guys above have said the hotter tunes usually yields the best mileage on long straight roads. Black smoke means too much fuel and loss of fuel milage.
