I know the star kit comes with a vortech fmu.
I have the HRC kit with a Vortech S-FMU.
I am running real lean and not getting the proper Fuel presure.
I want to turn it up a bit but I don't know which screw to turn?

Is the static pressure (the screw on the very top of the unit) or is it another one on the side somewhere?

Some let me know, I am running very lean and I need to fix ASAP

Thanks

*BUMP*

I know someone knows??
Is it the static pressure screw or is it a diff one???

I believe there is only one screw, to adjust the idle fuel pressure. The rise rate is set by the disc installed in the unit and isn't adjustable.

usually hrc uses the cartech unit. Does yours have a silver color? Unless hrc started shipping the sfmu, you have a cartech.

He has the vortech. It was purchased after the kit was installed.

the large main screw in the center of the vortech is for static pressure.

Yeah I had the cartec and it sucked so I got the SFMU vortech...

yeah I know the top one is for static, but is it the one I need to turn??

i don't know what static means??

Yes, turn that one while idling and watch ur fuel pressure guage, take it from 32 to 45-47

Cool thanks
Ryan!!
