hey guys, at what point (HP?) should i start upgrading the rest of my fuel system? and by the rest, i mean i already have a Walbro 255 hp fuel pump to feed my turbo set up. ive read somewhere that the stock fuel filter, pressure regulator, and rail are good up to like 400hp. this sounded a bit exaggerated so i wanted to double check before i go blowing good money on something that wouldnt be worth my time.
