Tee into the line that signals the ALDA and run a hose and gauge
into the cabin where you can read it

You tee a pressure gauge, such as the should-be-ubiquitous modern
pressure/vacuum MityVac, into the line from the intake manifold that
(eventually) goes to the ALDA. Put the gauge s

Only 8-10# IIRC.
Between 700-800 millibar under full load AND between 2000-5000 rpm.

What is the boost pressure supposed to be on a 1985 300Dt?
Only 8-10# IIRC.

.9 bar I believe.13 psi or so...
