Manifold pressure off MAP sensor?

Well, that's not the way that makes sense to me.
Absolute pressure makes more sense. And using ONE unit instead of two makes even more sense. Anyone who has flown or worked on an airplane with a constant speed prop is guaranteed to agree.
So get one of those gauges, like in Bill's picture, take off the cover glass, and paint a new dial on it.

I don't know about YOUR Jeep, but MY Jeep's propeller turns at a varying speed...

You had to open that can of worms.
No one needs to rehash the Hamilton Standard problems.
Yep, your receiver plug prop resulted in the death of a lot of good boys.

Looks like the hot rodders that install absolute pressure gauges tend to use aircraft surplus. You could always buy your own sensor and add a suitable meter of your choosing for the output.
14.7 more or less, or 29.92 Hg or 1013 millibar at standard temperature and mean sea level.
Could probably be gotten from one of those old center reading boost gauges with a custom faceplate and calibration.
