Fuel Pressure question...

Fuel Pressure question...
I know not everyone reads my build thread anymore so I will ask this on a fresh thread....
I install an adjustable fuel pressure regulator yesterday and it seemed to smooth out the car and it now picks up a little more above 5k... I set the pressure with the vac line off at 43psi....so its somewhere between 35-38psi with the line on..I don't remember what exactly..
Anyway, how much of a psi drop do you normally see from vac line on to vac line off????

Seems about normal....but we normally see a little more difference then that (for example: if we set it at 45 static and then hook up the Vac line, it drops down to about 32 ish range....make sure your FPR vac line is a dedicated line and source, and there is no leaks in the source, manifold and FPR too....
