From my understanding the vacuum line on the fuel pressure regulator provides constant pressure differential between fuel in the rail and manifold air pressure.
it's also limited to 50psi....so if youre seeing 75psi of fuel at 25psi of boost it's because you did something to achieve this.....correct?

If you add 1psi to the manifold source of an FPR it's like adding 1psi to the spring pressure. It's a simple device, I don't see how it could be limited to 50psi. It's very similar to a DSM FPR, the only limiting factor on them was volume, they'd get overrun with very large pumps, I think you guys have discovered this as well.
