If the measured value is not close to the desired value it indicates that the EGR valve is not operating correctly (sticking). The valves default position is fully closed, 0%. I don't think there are any other "desired vs actual" measures. I keep this list of 6.0 values in my van just in case I need to do some diagnostics on the road. I found it on one of the diesel forums stickies.

Manifold Absolute Pressure (PSI) (BOOST)

MAP is a standard gauge - but this XGauge is actually better than the standard one. It has a larger range which was needed because the standard gauge tops out around 37 psi absolute (about 22 lbs of boost), which diesels have no problem doing. This one should read well beyond 22lbs of boost.
?With a little tweaking you can adjust this to read boost as you said.
??To do this, just plug in the MAP code - get a reading from it with the key in the on position but the engine off, then based on the reading changed the last 4 digits of the MTH to whatever corresponds to your reading on this table
12.7 FF81
12.8 FF80
12.9 FF7F
13.0 FF7E
13.1 FF7D

?14.2 -- FF72
?14.3 -- FF71
?14.4 -- FF70
?14.5 -- FF6F
?14.6 -- FF6E
?14.7 -- FF6D
?14.8 -- FF6C
?14.9 -- FF6B
?15.0 -- FF6A
??So, for example if you got a reading of 14.5 PSI with key on engine off you'd change the MTH to 01220320FF6F and the reading should read 0.0 with key on engine off and would then show how many lbs of boost you were at when the vehicle is running.
