My perception on real gas
As an engineer, I hate "feelings" not supported by hard data. 1/4 tank left, went with premium. With tank down to 1/4 again, came across a station offering 93 ethanol free and filled it up again. ...

"If you disagree, fine. Post any legit article and I will read it."
I get it and I said I agree with you at least twice. With the caveat being if you "can" give it more fuel, or if you "know" what the actual fuel was.
There are plenty of scenarios where you "can't" give it more fuel, so the equal volume of alky laced gasoline will make less power, all other things equal.
Besides, when we're talking E10 and a max of 3% difference, unless in a very controlled setting, that is borderline imperceptible.
However, unless you're certain that when the OPs engine is running pure gas, it pulls enough fuel back compared to running E10 to put it at a disadvantage compared to E10 then your broad brush statement doesn't work.
All I'm saying is you 100% dismissed that it is possible for the OPs truck to run better on pure gas than E10 and that it in fact had to have been making less power.
Of course we're splitting hairs here, now, because apples to apples, that 3% difference is now likely 2% because there was 1/4 tank of E10 left in the tank upon fillup, or maybe it was 1.5% because the E10 was actually only 6% ethanol.
Again, I AGREE with you on the merits of alcohol content in fuel. But in an uncontrolled experiment it does not mean those inherent merits had any positive affect, and as you claim, they could not have possibly had ANY negative effect which is countering the OP's butt dyno.
