Except that when the car is at 0 PSI, that's actually 14(atmospheric)PSI. Every additional PSI of boost pressure is added upon that pre-existing 14 PSI that is always around us. Keep in mind, nature will not tolerate a vacuum. So the Vacuum readings on a guage is actually just low pressure, not truely a vacuum. It's just less pressure than 14 PSI.
