Mreid,

Maybe I am stating this wrong. I am simply stating that pressure at say with a Weber IDA 48 is only important because of the needle and seat.
So, if recommended is 3 psi and you run 2 or 4 psi you would probably not see a difference unless the needle has a minimum 3 psi cracking pressure. Also, if you exceed the 3 psi to 4 psi this may hold the float down from excessive pressure. If the previous condition do not happen then, there would be no difference in performance.

Correct?
