High pressure any where from 200-325. Low pressure around 65-70ish. But pressure doesn't really tell you much about how the system is working. You also need to check your superheat on the vapor line and your subcooling on the liquid line. If you don't know what I'm talking about, then you are treading in very dangerous territory of doing serious damage to your system if you are trying to adjust the charge based solely on pressure.
