Hey guys im about to setup up my first turbo rig on my 96 honda accord ex. Base fuel pressure is 40-47psi (without vaccum hose). And im going to use a FMU for my fuel managment.. I know i should probably get a chipped ecu and run a program but im going to do it this way for my first time to get used to turbo...My question is does anyone know about where my fuel pressure should be at for like 6 and 8 pounds of boost... i know that the different fmu pressure springs (like 8:1,10:1,12:1) cause the fuel pressure to go up that amout for every pound of boost, but what FMU pressure should i use? im probably going to have a all stock fuel system becides fuel pump, and dsm 450 injectors.. Hopefully that made since to you guys... Get back to me on this one, thanks mekal.
