If you are on charge, ie with stage 1 EPROM with 1.1 bar TC pressure, your fuel pressure should be 3.5 + 1.1 = 4.6 bar.

So roughly then, do you raise the fuel pressure say 1bar for every 1 bar of boost increase from standard?? At what sort of pressure would injector lock kick in at?? Is a cosworth fuel regulator progressive with boost increase?? Sorry for many questions but I like to learn
