Shane is just getting technical. Airflow is what causes fuel cut. If you are using a SAFC though, that will lie to the ECU and tell it that it has less airflow so you don't hit fuel cut. I run my FPR at 45psi and John is running 50 psi I believe. I have heard that over 75 psi you start to run the risk of getting too much dead time at high RPM's. The extra fuel pressure makes it harder for the injector to move.
