Default fuel pressure

I am not turbo at this moment(i was but my DIY manny cracked like a *****) but i am haveing some fuel pressure issues. I am running the VAFC hack with DSM blue tops and a 255lph intake fuel pump. I have a B&M FPR from along time ago and the cars fuel pressure bounes at 40-45 psi at all times even at WOT. Would going back to a stock FPR change all this shizzit.


For sake of not starting a new thread, my VAFC is set at -26% across the board on my N/A accord and my plugs are kinda white, not brown like they should be. Only thinhs that havent been checked/replaced is timing and O2 sensor.

I would check the fuel filter if you have not replaced it already. Your fuel pressure regulator could be faulty as well or maybe a clogged return line. As for the white color on the plugs i think the white means you are running lean as hell . Why are you running -26 on your na accord i am curious. I would set at zero unless you are running bigger injectors.If anything i dont think a vafc helps much on a naturally aspirated vehicle but i could be wrong.

I have checked and replaced my fuel filter.

As for my VAFC i was once boosted and had to go back to N/A until i got a new manifold(which is sitting right next to me). The only reason im using those setting is too see if my settings were too lean with the VAFC since i dont have my wideband hooked up to my stock exhaust.

Im going back to a stock FPR and ill check all my lines.
