i just installed my paxton fuel pressure regulator. i set it somewhere between 45psi and 50psi with the vaccum line off. i attached the vaccum line and it goes down around 35psi to 32psi. i hit the gas and it jumps up to 40psi. my car runs better than ever now. my question is that when i hit the gas my fuel pressure will go from 32psi up to 40psi or should it stay at 40psi all of the time? thanks for your help in advance.
