Really all efi systems should be this way. People get lazy or think there is no reason for it but there is.
So, if you understand how it works then your saying it is correct for the injector to flow more fuel at an idle than it does at WOT?

of course not. But referencing the regulator will lower the fuel pressure at idle/cruise/higher vacuum areas, and increase it as the load increases and vacuum drops. In an adjustable system (not the EZ EFI) you can set the injector pulse width to compensate for a non-changing fuel pressure. Now an injector has a minimum amount of time it takes just to function, so if you have a real large (or too large) injector you can have idle issues and the lower fuel pressure with referencing would help. But I've run 95# injectors without issue. I boost reference for blown engines, but again have done many N/A setups without referencing and never noticed a single hiccup.
I am not challenging your knowledge, I'm just a home hobby tuner guy. I just can't see the issue you're describing.
