The code for the compressor should just check whether the pressure switch has activated or not. The program cannot change what pressure activates the switch.
So if the compressor is running and you are only seeing 20psi and you have your regulator in the system here are some things to check:
1. Leaks as already mentioned. Since you are only seeing 20 psi, your leak would be large enough to hear. Also make sure all of your tubing is pressed firmly into the fittings. As mentioned above non-square tubing ends will prevent tight seating so check that. Also give each fitting a little tug to make sure the tube is in.
2. Make sure you have your regulator set up correctly. If you look closely at it, you will notice an arrow that indicates which way the air should flow. I believe the regulators have 4 ports. Input from the air tanks should go on the starting side of the arrow. Output from the regulator on the end of the arrow. Pressure gage on the top. Plug on the bottom. Finally, turning the regulator clockwise will bring the working air pressure up.
