stock 1g fuel pressure is 37psi, and 2g is 43psi, if you had a stock gs-r with, 48psi you would be flowing considerely more.

you can do sum self testing if you want by opening one injector off the fuel rail...get a cup or cylinder with measurements on it and if u have a FPR...adjust different pressures until it fills the cup or cylinder up correctly...just an idea!

You need 4x the fuel pressure to flow 2x more fuel. If for some reason your stock gsr was running 48, you'd be flowing 14% more. Otherwise, it would be ~6% more if you were running the stock 42psi.

most injectors i have seen are flowed @ ~45 psi
