Huh??? On my 230 hp O-470, I cruise at 23-squared, without any fancy
engine monitors. Using the "pull-until-it-feels-about-right" method of
leaning, I get 12 gph.

I can lean to that fuel flow without any undue engine sounds, too. But my
EGTs go well over 1500 degrees, and my CHTs push 350 when I do.

I would rather burn a bit more gas.

On a side note, as I asked you earlier, what part # spark plugs are you
running? I am curious due to your undue propensity to fouling while
running avgas.

I have no idea, and I don't have my logs handy. However, as I said, I will
be replacing them with a hotter-burning plug when they wear out.

Of course, without all that lead fouling, they may never wear out!
