Default fuel preasure and RPM's

ok my question ! my cars rmps is alil jumpy cause of my cam but nothing serious 900 , 1000, 1100, then back down to 900, and so fourth. i notice my fuel preasure gauge jumps around with as the RPM"s jump around , WHAT RPM DO I WANT TO BE WHEN IM CHECKING MY FUEL PREASURE ?
