Fuel pressure anyone actually measure it?

Has anyone ever actually checked theirs? I have been told the v6 cars run at 60psi, old school Ford was always measured at 43.5 psi or basically 3 bar, I know my vette was in the 50's stock and the Mustang has an early return system like the vette, just wondering?

Its actually set at 55 psi. The system is set by the fuel pump. There isnt even a sensor in the system to measure fuel pressure. That's all in the computer. I have my system set at 65 psi on the fuel regulator. We had a fun time figuring out that the computer is just told that the fuel pressure is at 55 psi. So even though im running 65 psi we tell the computer its only seeing 55psi. If not then the computer goes ape and doesn't like life.

If you need a fuel system let me know mine is looking for a new home for half the price of building one. lol

Would it possible to get this info onto ***? It might come in handy one day.

info on bumping it up

how do you adjust fuel pressure ? And how did you trick the computer.
on my old school 5.0 I just bought a adjustable regulator .Can this be done with the 3.7 ?
I would like to bump it up a little due to the CAI has made a small lag on take off because of all the extra air over fuel at take off
