It's my assumption that most tunes are aimed at increasing performance. Performance is very likely to have an inverse relationship with fuel economy. That is, as performance is increased or improved, fuel economy is decreased or lessened.
Out of curiosity, what app is this?

So you are saying the HF tune decreased your mpg? I feel the same way with my custom Hf 92 tune. I am returning my truck back to stock on this next trip towing to see if I can get a little better mpg. Will definitely put the tune back on for daily driving though. Truck drives so much better when tuned.

I run mid grade gas, it’s stock tires and 4wd. Funny some people don’t believe me. I drive for a living so I go the speed limit every where I go. If the speed limit is 70 I go 70 not 75. There’s no need to fly around everywhere you go. Keep the left door shut and the truck moving forward and you can get where your going safely and in a timely fashion. I averaged 25 over the course of a 560 mile one way trip. Coming home I got 24mpg. I was surprised at the mileage but i know I’m not the only one getting over 20mpg on the highway.
And yes my truck is a hemi, it is stock, and I only have 4600 miles on it.
