how can I run 4 bar fuel pressure on a LT1 I did 24x about a year and a half ago and I want to take advantage of another feature of this PCM and run 58psi fuel pressure. I've been trouble shooting jerky cruising and unplugging the vacuum line for the fpr helps it run smoother so I figure 4 bar with give me even better atomization. Ideally I would run a full LS setup from pump to fuel rail but with the LT1 fuel rail is there any way to go returnless? If not, can I get a LS1 pump and maybe an adjustable fpr? Currently running Ford SVO 30# injectors, walbro 255, everything else stock return style LT1 fuel system.
