If you have a 3 bar sensor with 4 bar cal you can get a reading that is off in that direction. There are also 1 bar sensors, 2.5 bar sensors...

Using ms3 pnp pro for 94. Being told by DIY to use mphx6400 settings. Settings are confirmed. No other map sensors from the dropdown menu supply a 100kpa reading at engine off.

Well, that's a problem. If it isn't about 101kpa it isn't right.

Clean all your ground wires because they can be a factor.

I guess I have wired something incorrectly to the options plug (vvt, ebc or knock) that is causing the issue. After some troubleshooting with DIY, I had left the options plug unhooked and the MAP is now reading spot on.
