Turn the key on, don't start the engine: 43.5psi, +/-2.5psi, so 41-46psi is OK
Start the engine, pull the vacuum line off the FPR: 41-46psi
Engine running, replace vacuum line: 35-38psi (can be higher if you live at a high elevation, or if you have a radical cam with little vacuum at idle.)
WOT: Pressure should return to the "no-vacuum" value, and stay there.
As you drive: Pressure will fluctuate between the values with the vacuum line off and on, depending on throttle movement (vacuum)
