I don't understand how 70 or 100psi on the low side would effect the injector flow when the low side feeds the DI pump and the DI pump feeds the injectors. I would think the DI pump pressure would have more of an effect on the Injector flow. As long as the DI pump gets enough fuel from the low side to maintain it's pressure, then it shouldn't really matter what the low side pressure is in theory but I could be wrong.

That being said, I am not saying to buy the LPE injectors. Several have used the FIC 30's on big HP builds. I was just pointing out that the LPE's flow more.
