    Hey, Im installing Accel 309cc injectors and an aem high flow fuel rail, with an adj. fuel regulator and a walbro 255lph fuel pump, I was curious which is the best psi to run at since i dont have a air/fuel ratio gauge and I'm running a P73 ecu from an ITR, in an LS/Vtec Obd2 96 civic coupe, if someone could give some heads up I would appreciate it, thanks

    you cant really go by other peoples psi rating on there fuel regulator because all motors will be different....it all depends on what you have done to the car...like i,h,e.....plus its best to do the tuning at a dyno...so i can mostly gaurentee everyone else here will tell you that...sorry bro.....just search around your area for a dyno... :mrgreen:

    put the stock ones back in. you'll do more harm than good.
    the oem computer is designed for oem injectors and oem rail pressure.

    if you change 1, you should change all 3.

    you can tune down up to 450cc with a vtec controller.
