Engine vacuum is not measured in pounds per square inch (PSI). The most common unit of measure of vacuum for automotive engines is inches of Mercury (inHg). At idle most helthy engines should develop a steady 17-20 inHg. If you have less, it could be a number of things including improperly set timing, a vacuum leak, improperly air/fuel ratio. Check with your automotive technician or other qualified individual for greater detail as to what engine vacuum should be at various rpms/loads.
