Genos Garage sells a boost bolt or you can drill and tap into the intake horn

on the intake side of the head behind (towards the cab) the injection pump is a plug that you can take out and put a fitting in there and that works perfect

Look for the silver/black sensor. That is the easiest place to put the boost sensor. There is a 1/8"-27 plug in there.

Well, if it is like my dad's '93 was, you should see anywhere from 0 to about 15 psi. He hardly got over 12psi, even pulling heavy loads.
