Fuel pressure reg. Ideal pressure for a stock truck

I just bought a dieseloring.com fpr housing ( Fuel Pressure Relief housing - Billet Aluminum w/pressure shim springs ) and was wondering what is the ideal pressure for a stock truck? all i really have done is a custom tune and an 6637 intake for now but read about ppl suggestion diffrent pressures at all times. This kit comes with 3 springs to adjust press. 58-61 psi silver spring (Stock pressure)62-65 psi gold spring,67-70 psi black spring. I have always read about ppl shimming the fpr which is why im wondering now how much is good and how much is bad? im interested in a little more performance but dont really want to kill my mpg either.

You will not gain performance with this mod. You will set it back to the way it was from the factory which is as good as it gets. Above 55 psi is all thats required. keep in mind more psi does not equal more power.

I use the black spring and have no issues with leaks.

Fuel pressure on a 7.3 has little if anything to do with performance. So long as you can refill the injector before the next injection event you will gain nothing.

Every truck, every injector has a sweet spot for fuel pressure, when I ran stock injectors I kept it at 74psi or so, with the stage 2's it was 65psi and the hybrids I have now are 62psi....

Otherwise as was said before, above 50 psi and your not hurting the injectors, above 75 your just working the pump hard.
