    So i got 00 civic si b16a2 and i had 440cc injectors and fuel regulator when i got the car and the car would run so good and pull super hard with vtec
    but the gas was killing me so i had to change the injectors to stock b16 and now the car still pulls but not as hard as before my Question is what should be the FUEL Pressure i got it 43psi at the moment or what i need to do/ get to get good miles as well as performance??

    did the car run rich with the 440cc injectors before ?
    im new here and need help !
