Look at the fuel press gauge. It should be reading boost plus what ever you set the fuel pressure at at idle ( no boost ). I have used an in car camera so I can see the boost gauge and fuel pressure gauge at the same time.

Another way to do it is make a pass and look at the boost gauge going through the lights. Make another pass and look at the fuel press gauge going through the lights. If you are running 15 lbs of boost and you set the fuel press a 7 lbs at idle, your fuel pressure gauge should be reading 22 lbs going through the lights. Make sure your boost reference line is large enough. Think I use a -4 line.

on the trans brake i here the turbos wine but the fuel pressure stays the same and the car shuts off
You have issues then... make sure of the line going to the regulator is working... all its doing is supplying pressure on the back of the diaphragm to assist the spring

this time with the line off the carb hat fuel pump on blow some compressed air bye the line fuel pressure raised up 10 # so it sounds like it works vacumn lines to small
Even a small line should react.. just slower to respond

What is the source of boost to the regulator? Is it above the throtlle plates or below?

The boost reference should be what the injectors are seeing inside the manifold (assuming they are in the manifold). Manifold pressure - below the throttle plates.
