This is a preliminary question / discussion, I'm curious about theories but WILL post tune and log soon.
Ever since I recently went Speed Density with a huge intake and throttle body, it was pig rich at first of course. Good enough cold / hot start, idle, drivability and power for a baseline and I'm dialing it in daily.

I'm finding that as I lean out slowly and log the higher gears are pig rich still as the lower gears are approaching ideal(ish). As a matter of fact they are progressively and predictably rich.
(WOT / PE)
For instance as I go through the gears something like : 12.8, 12.6, 12.4, 12.2, 11.9, 11.0
I do have 4.56 gears
It's because my VE table is not dialed in proper isn't it. I do understand the concept that all is sees is VE cells now as opposed to before where above 4k the MAF was snitching better.
