I was just wondering how fuel pressure regulators come in to play when tuning your car. before when i got my tune with my ca, i had a walboro fuel pump, stock 370cc injectors,and megasquirt setup. NO FPR.it made very nice power. 220 somethin at 7 pounds.i think i only got like 175 to a tank too btw lol.
now if i had an adjustable fuel pressure regualtor to turn up the fuel pressure before i had got it tuned, what would be the results. more power? better fuel economy? worse? etc.
can somone exlpalibn how this works to me. k thanks
