It takes xyz horsepower/torque (fuel) to move 8000 pounds of rubber, steel, and glass through the air and over the road at 70 MPH on the flat. No tune is put to the test here - but I invite the experts to scrutinize my words. There are fueling strategies and transmission strategies that combine to improve economy when you're not in cruise control on the flat. Traffic, variable speed roads, and mountain climbing is where the 60e and 80e can strut their stuff to deliver performance and increased economy.

Yes you can optomize your fuel economy better in a tune that is specifically designed with certian changes within the fuel tables at crusing speeds. This why we reccommend using the econo over stock as your daily driver tune. Does this mean that eveyone driving in the econo tune you will be guarnteed a increase in fuel gains, Nope. Why? Because no two trucks are alike just like no two drivers will drive the same. Many other variables as well. Driving speed has the largest impact on fuel consumption. No one can drive 55 anymore and who would want to. Around here it's called a traffic jam.
Between 68mph and 72mph my Excursion can at times get 19mpg on a highway trip.

Thanks for chiming in there Diane!
My humble opinion on this: There are 80HP tunes out there that dump fuel, but are not very easy on the wallet or the air. The 80e is clean and economical in relation to those more wasteful tunes. I think DP can be forgiven for using the 80e moniker as it is completely appropriate and separates it from something like the 100 performance tune.

[The 60e and the 80e give substantial performance gains without the smoke and the loss of fuel economy.
i get a pretty good amount of smoke in 80e light throttle taking off and hitting it while rolling and none in stock . 80e pulls much harder but im considering live tuning to get my throttle pedal same in 80e as stock and maybe clear some of the smoke but i dont want to lose the xtra power
in performance i dont care as much as im only in it for performance . i havent tried the tow tunes yet havent hooked to anything lately.

I've been running DP's F5 chip sense 07. I pull a 48ft race car trailer and I'm gross out at just about 33/35,000lbs and get right about 14.4 mpg using 80e, and without the trailer I get right around 24/25mpg. I just sent it in for a update and was told not to pull in 80e cause the trans shift point are not right for that kind of weight, so he said try the 80tow and see what happens.

You do know that the overhead will be wrong with a chip. I was showing over 50 MPG for a while with my chip. I know I can't even get close to what you are getting.

Its from the overhead, but I can go 500 miles on a tank and that come's out to about 13.2mpg. back in the day when I was pulling my 28ft with my 92 gassier (460) I got 5.5mpg all day, so 13 with a 48fter I'm good with that.

Between my stock, 80e, tow and race tune, there is plenty of hp difference, but what separates these in addition to fueling is the trans tuning. Econo has a fast throttle "tip in" so you'll go easy on it, and gets up to and holds a high gear longer, etc. That's really what makes it econo, IMHO. The race and tow tunes also do things better for their intended purpose. I really like the race tune shifting, it keeps the power right there ready to go. Even if someone did not care about more hp I'd recommend tuning for the sake of the transmission. And a 6.0 cooler.

Egt are at about 900, but they climb pretty quick when I get on it.
