fuel pressure regulator questions???

I have a 96 and have read about the fuel pressure regulator shim. My fuel pressure was at 50PSI and installed the California emissions regulator and it went to 80PSI. Ford spec is 50-70 I believe. Things I have read say not to go over 75PSI. If the Cali spring gets it to 80 and it is a ford part what could it hurt? The truck is more responsive and idles a lot smoother.

I don't believe the gauge is liquid filled but a snap on gauge fluctuating between 75-85 at between 3000 and 3400. at idle it fluctuates between 75-80.

Not sure if its hurting at all if you say it runs better, I have a Cali model but have yet to check fuel pressure as it has yet to let me down

Anything above 75psi, and you start to run the risk of damaging injectors.

No. What I am saying is that it is not supposed to see that much pressure. A stock Cali model truck does not see that pressure either. My Cali model truck sees 70psi(it is a SD, but same concept).
