Take a look at this attachment and see the 125/30 PSI portion. I suspect this is the issue. When you replaced these parts did you add oil? If not, I would suggest pulling the entire system down and evacuating it then add the proper amount of Freon and oil back in. Then check the pressures again.

Here is a guide on this process:
