The ECU doesn't "know" what your fuel pressure is. You just tell it the injector CC. Which is fuel pressure and flow of the injector combined.

I've heard of people saying that the Walbro increases the fuel pressure, I'm just saying I didn't see that happen on my car.

I would love to know as well which one fits.

I haven't looked into which 4-bar FPR would fit. I don't like the odds that one would be a direct bolt-on.
