43-45 psi w/ vac off is stock.

Adjust it to where you need though (isn't that why you bought it?) I wouldn't go below like 32-35 psi though.

It's hard to give you a good base fuel pressure number.
All Supra's with your setup will be slightly different from each other.
You need to monitor your vf like grim said, this will give you what you need to know.
