8psi what fmu disc?
 

I'm currently putting together my hmt on my 90dx[mpfi done].For fuel I'm using a inline pump,missing link and vortech fmu.I just ordered a recalibration kit that comes with all the discs and was wondering what disc I should run for 8psi.It currently has a 12:1 in it but that would give me 130 something psi of fuel under boost which is way to much.I realize this is a ghetto way of doing it but this is all I could come up with locally.Thanks

12.1 reason why any less runs lean been there done that like 6 years ago.

which injectors?

Injectors are stock 240cc.Thanks for the help.

12 * 8 = 96

96 + ~42 = 138

Yikes...138psi of fuel pressure just scares me :o

I have (1) set of DSM 450s, (1) set of saturated 370s, and i think 2 sets of 290s or 310s that are sitting there doing nothing...well they aren't mine, they are my garagemates and im sure i could get him to sell them to you...

Get your ECU chipped bro!

I think for now I will thread the actuator rod to turn down the boost.I'm interseted in the 310's or 290's pm me on a price if possible.I will get the ecu chipped later on when my other bottom end is ready.
