~21mpg after tune.

Curious how accurate the gauges are when it comes down to the AVG mpg? I recently changed the oil, rotated and balanced my stock size Revo 3’s and loaded a custom 93 performance tune by 5 star which I am very pleased with. I was averaging 18.2 before the tune and changes I mentioned above.

wanted to know what the best MPG you guys have gotten was and if my experience today was a fluke. I’m not out of my tank of gas yet, but will calculate exactly what I was getting next time I’m at the pump

I get..10....uphill, downhill, with a headwind or pulling the hinges off the gates of hell. On 93.

I get between 12.5-14.5 with my Goose E50 tune.

14.7 mixed/15.4 hwy 91 Goosetune, has not been reset in a while.

Oh, live in Texas. Speed limit to town is 75 mph, soooo...

I’m just curious if anyone has ever tested the accuracy of our Lie-O-meters as well. I’m sure there is someone who has. I just injured my foot this morning so I won’t be driving anytime soon to figure out how much actual MPG I’m getting vs what’s being displayed on my gauge. But I doubt it’s actually ~21mpg.

Mine was 6% high. Once I entered the 0.94 correction factor, my reported mileage dropped about 1 mpg. My actual mileage ... didn't change.

The calibration is a bit off - it's not accurate when stock and definitely not accurate after being tuned.

Here is how to fix it: https://www.f150forum.com/f118/fix-inaccurate-mpg-display-2-minutes-421912/

Could also be weight and size different from the Dueler Revo 3 to stock BFG. I'd love 20 real MPG.

Not really a fluke, I was just under 22 while driving cross country. fresh oil & alignment, inflated rotated tires, clean air filter on 93 tune. And when calculated out, came out to 21.4 mpg.
