I hooked up the pressure guage and am reading over 100 psi at idle. WTF! What would cause the car to do something like this. That is the reason it won't idle I guess. I have a stock GST fuel pump in the tank, Vortech FMU, and a MSD inline pump.

100psi? Would your engine even run with that much fuel at idle?

When my FMU went bad I was also getting 100psi of fuel press at idle.
check your fmu connections or fmu itself. did you open it up recently? i broke mine by completely taking it appart and then putting it back together, did not know I was not supposed to take appart the bottom half of the unit.

I haven't taken the FMU apart. How could it just break? As of right now I disconnected the inline pump and am just running of the stock GST pump in my tank. I still have to break it in so I won't be boosting anytime soon anyway. I am thinking about just buying a Walbro 255 intank unit.

That is definitely too much fuel at idle. Did you remove the stock FPR when you installed the FMU? I would double check the FMU hookup to make sure nothing is reversed. I'm not sure about the FMU that you have, but is there a knob or screw to adjust the static fuel pressure?
