All of the fuel injector capacity figures that I have seen are at a pressure
of 43.5 psi. That is the pressure I use for my Renesis.

There is a calculator on the lower part of this page that will tell you what
injector flow you will get with the fuel pressure changes.

Subject: [FlyRotary] Renesis fuel pressure question

While perusing an old document describing the then-new Renesis, I
noticed that the fuel pressure was spec'd at 392kPa, which if Google is
to be believed, amounts to 52psi. How many of you are running pressure
that high? If you're not ( I seem to remember 30-35 for a lot of
installations), how much does that affect injector capacity and fuel
atomization (efficiency)?
