vortech SFMU tune

[Boostin95RST]

i bought this SFMU off a buddy and i dont know how to tune it. i put it on and i was running very rich so i got the fuel pressure guage and it is saying that im at 105psi. i dont know how to lower it. i dont know what disk is in it and i dont have the other ones. what do i adjust on the sfmu to lower the preasure? i have 450 injectors and a 255 fuel pump. maybe get a smaller pump?

Get a proper 1:1 ratio FPR and proper management. Screw that FMU, they are complete and utter garbage.

Why do you think all the getto honda turbo guys blow their engines all the damn time on FMU's?

How incredibly helpful, haioku-rocket...

There is a set screw on the top of the SFMU with a nut holding it steady. Loosen the nut, and adjust the screw until fuel pressure is where you want it at idle (loosen for less, tighten for more) then snug the jam-nut.

Get your discs and springs from Vortech.
