So the stock EVO8 injectors are rated 560cc@____ PSI...and are 3ohm resistance (low impedance)....

Does anyone know what PSI the injector rating is at?
Does anyone know what PSI is present on the fuel rail at idle? Under full boost @WOT?
Does anyone know what the ratio of the Fuel Pressure Regulator is (1:1, 2:1, etc)?

I searched for a good 2 hours and found the flow rating but no PSI numbers, and the impedance...but no fuel pressure numbers.

Thanks for any info/help findin the info.
