Re: Fuel Pressure suggestions
Mine is at 47 with 48 lbers and a walbro 255 pump. It really depends on what you are tuned for because the pressure will affect how much fuel is being injected. I just set the pressure there, tuned it, and left it alone.

Re: Fuel Pressure suggestions
What ECM are you using? Normally you would set the pressure at 43.5 and tune it there. What pressure were the injectors rated at? If rated at 43.5 and you are running at 55 you have increased them to 31.45 lbs
