OK, now we have some information. Your original pressures were WAY too high, both low and high sides. That means either you have air in your system (like system was evacuated properly before adding refrigerant) or you have too much R134a refrigerant, problem with coolingg fans/fan clutch, or a combination of all. Your newer pressures are better; but a good rule of thumb is that high side pressures should be about 2.2 times the ambient temperature, or like 220 psi on a 100 degree day. So 325 is still too high, either too much refigerant or fan/fan clutch issue compounding the problem.
