Do you get that part?
Then the ecu just tunes the actual fuel curve and not the fuel curve and the pressure differential too. This gives the ecu a better ability to tune at the lower PW for any injector size.
If line length was an issue then your rear mounted regulator wouldn't work under boost. The long line will make the change slower but it will still work just the same.

I get it and I give up..............
