Rolling reset. Mixed driving, 30 to 60 MPH. Some cruise control, mostly not. Some uphill, some downhill. No tail wind. Some braking included. One stop and wait for oncoming traffic before turning left. One slow down for then pass slow moving farm equipment. One complete stop at stop sign.
First pic is stopped at stop sign. Second pic is stopped at destination. Obviously there was acceleration back to speed between the two.
Of course this MPG can’t be maintained in everyday driving do to number of stop starts, time idling at red lights, etc. At 58xx miles my lifetime average is 20 even (actually that was reset at about 100 miles on master ODO).
I’d love to tune for more but it would have to be quite a bit to justify the tuner cost and potential warranty issues, whatever they may be. I have no idea what MPG a tuner will yield and that’s why I was asking about larger sampling results.
For now, I’m not disappointed with factory tune.
Edit: About a mile after the first pic I turned the A/C on to defog windshield as it started raining hard. I also had to turn the cruise off because there was too much water on the road. I could really feel the water adding rolling resistance. If not for that, the final MPG would likely have been higher.

I'll be very happy if I can get 20. I don't beat on the truck at all, in fact I drive like the olde guy I am. With the anti-aerodynamic mods I've done, 20 will be golden!

Continuation of my rolling reset a few posts back.
Still too small of a sample but it includes about an hour of downtown Minneapolis driving complete with a bit of stop and go traffic.
The second pic is running average since the day I got the truck. It was last reset around 100 miles total on the master odometer.
I doubt I’ll mess around with tuning as I expect the existing factory tune MPG will improve as the miles increase. My last truck (2001 5.4) peaked just above 18 MPG at right around 120K miles.

My tuner has shipped!!!!!! Hope I get it by Thursday, I'm going downstate Friday. It's a 400 mile round trip and would like to see what improvements I might get.

At least that's been my experience anyway.Just keep in mind, you can fill up on 93 and run any tune you want, any lower octane fuel you fill up with make sure the tune matches.

LOL, oh yeah, I plan on kicking it a few times. But, I can control myself, sometimes. I wonder if there'll be any change in the exhaust tone at idle. I know in my Stroker, there was no outward hints, until you kicked it!!!! I really haven't been around many gassers I did mods on in years, been diesel for quite awhile, and gassers were left alone. In fact, the last gasser I was really interested in, had a 4 barrel.

It will be a deeper tone, it was the 1st thing I noticed after I tuned mine, even made a post inquiring about it and others confirmed it.
Don't wait to get the info together for the custom tunes because even though the canned tunes are good, the custom tunes are ten times better.
