Were these pressures obtained with the compressor on? What you've quoted is representative of an equilibrated system with the compressor off.

Several factors come into play (ambient temperature, freon charge level, oil charge level, engine RPM, etc.) but with a R134a charge and a functioning compressor you should see low side pressures below 50 psi and high side pressures over 300 psi.
