I have posted this Q many times but no one seems to answer me so here it goes one last time. Is this setup right, I have searched and searched and this is the only way I have found to hook my fmu up.
The only problem is when I start my car it idles fine but when I give it gas it wants to stall.
Im sure the reason is because im not getting enough fuel pressure in the fuel rail,
But everyone says the 12:1 fmu is the way to go with the 420a turbo setup.
Someone please help me I want to raise some hell again!!!!!!
 
I've posted this a few times before...

You shouldn't have needed to drill a hole in the fuel rail; the test port with the Schraeder valve removed would've worked fine.

No, the FMU does not replace the stock FPR; only an AFPR (i.e. Aeromotive) or a SFMU can replace the stock FPR. If you took off your FPR, put it back!

The FMU cannot control idle (and vacuum) fuel pressures properly, which is likely the reason you are stalling so much.
