I don't think the vortech fmu knows the stock fuel pressure and compensates. I think it's a diaphragme tipe thing that starts counting at 0. Could defenetly be wrong, I haven't recieved it yet.
well from what i understand it will add 10psi of fuel for every 1psi of boost so it will add a total of 50psi. so it would be total of 80something psi because stock pressure is around 36psi.
are you referring to me and the fuel pump? If so I was told originally that my fuel system (stock pump plus the vortech) was a total of 255lph capable at high pressures.
Their website says 50 gph at 70 psi... whatever that converts out to... I guess somewhere around 255 based on the conversion I did online.
