I take it you have an aftermarket ecu in there???? otherwise you should be hitting fuel cut at 1.6 bar.
14.7 is 1 bar which depending on ecu could be about right.
If you are running a standard ecu then something is still not right with the way you have things connected. Check all pipework.

Im confused abit, you said your car was hitting 20 psi which is approx 1.6 bar.
If you car is only hitting 16 psi then it shouldnt be reaching the fuel cut.
Was the car running correctly before you fixed the hole? what caused the hole? does the car still run a dump valve?
