let say the low side fuel pressure is at 45psi and I run out of hpfp at 600hp on e85. would getting that low side fuel pressure up to 60 or even 70psi help the hpfp go any farther?

I am looking for someone that has tried this in the real world and either saw an improvement or didn't see an improvement.
