Since your sig does not show what you have (hint), I will hazard a guess that it is the 96 in your handle. In that case, you should idle around 38-40 p.s.i. If you unplug the vacuum line going to the FPR (it goes into the intake manifold on the passenger's side) it should jump to about 43.5 p.s.i., give or take a couple due to manufacturing tolerances.
