I just swapped out my 5 ton condensing unit, I have a goodman air handler , I installed a used known good trane xl13 condenser . Both handler and condenser are r22. I have 150 psi on high side, low side almost goes into vacumn. 70 degree day, 90 degree roof temp.

first off you should have a four ton unit. what is your super heat? is it pulling attic or outside air?

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.
