I can't do much more than I do now on stock 235's. If I try to boost, I spin. If I boost a little it spins a little. That and my OD is having issues.
FWIW, my old w250 manual ran those first 2 times you have listed. Your auto is doing good.
I had more than 3/4 of a tank. I also run bald Firestone Steeltex tires in a 235 width out back. I had my foot on the throttle just enough to take the slack out of the TV cable, so I was still under 1000 rpms and thus making zero or near zero boost.

I have a Cummins low pressure piston pump and factory fuel lines, which I believe to be 5/16" both ways. I've never had this issue before on the street or dyno. Kind of puzzles me.
