Why would the fact you have low vacuum and it being a rising rate regulator not tell you much?. With an adjustable fuel pressure regulator you should set it up on a fuel pressure guage properly not guess it. You can use your boost guage to add or subtract your inlet pressure assistance to the regulator. Maybe im missing your point. explain? The reason being is you once said your cars std injectors were on there limits when it was on the rr at 17psi. by knowing your fuel pressure it may tell a bit more. A few extra psi on the fuel may make a few extra ponies if it allows that extra boost.
