Default The correct fuel pressure

I am finally getting ready to put my kirban fuel pressure regulator on. Any idea as to what I should set the fuel pressure at on my 94 cobra? My mods are full exhaust, intake, mas, and t/b.

I know one of you fellas have to know. I heard that for a mustang with a stock fuel pump you should lower the fuel pressure, true? what is the stock fuel pressure going to be at? With my mods with PSI will be best? Thanks in advance!

It should be 35-45 with the vacuum hooked up and 45-50 with it off. Mine is set at 40 with vacuum.
