SAFC II & adj. Fuel pressure reg
 

ok i need some advice

I have installed my apexi safc 2 and already have a walbro 255

and am planning to install s13 injectors

do i need an adj fuel pressure reg?

im planning on using the s13 pressure reg.

i dont think i need an adjustable one as any fuelling corrections are done by the safc am i right or am i missing something

will an adjustable reg have any benefits bearing in mind im probably only going to 220 bhp at the fly

See how she preforms on the standard s12 regulator. It should be ok as your changing for bigger injectors.I shouldnt think you would need to force more fuel through. Are you setting it up yourself or at a rolling road?

iv installed it my self and it up and running i plan on putting s13 injectors on and turning the fueling down by 27% across the rev range to get it running then drive it carefully to someone how knows what there doing
