2G Fuel Cut?

[Can6l7bus]

After doing some research on why my car is getting fuel cut, I'm pretty sure it has a boost leak (running really rich, running a heavy vacuum, sluggish while revving and wont pass 4500rpm).

After I was told about the FPS, I checked it out and realized the vacuum lines where disconnected and removed completely (nowhere in sight) but the sensor was still plugged into the harness. I think it was disconnected because the car had a SAFC installed previously but was vandalized and SAFC was cut right off of the dash board (while previous owner had it at body shop). I have removed the SAFC harness into the ECU.

Does anyone know if the FPS has any hand my this problem? I know one vacuum line on the FPS comes from the intake, but where should I connect the other side to?

Thanks for your help, any help is greatly appreiciated with this headache

The fps shouldn't be causing any of those problems.

The one vacuum line comes from the intake manifold and goes to the fps, and the other line goes from the fps to the fuel pressure regulator.
