For the sake of "closing" this case.
I installed an aftermarket fuel pump (thanks for the suggestion @
Brz866) as well as the fuel starvation door. I've had a couple thousand miles on it without a single issue, even when giving it the beans on hard left freeway entrances that historically caused the engine to starve.
Next step is flex fuel so I don't have to reflash when I have to switch back to 91 in the winter. Thanks for your help all.
