New AC parts didn't go as planned

Installed a new compressor and condenser in the disco. AC worked prior but not well so when the old compressor started squealing ifigured it was just old and a new one would have the system working better.
Installed the parts and vacuumed the system for 45 minutes. Waited 30 min to confirm it held vacuum. Added 2 12 oz cans and weighed in the last 4oz.
Low side is 45 to 50 psi
High side is 215
AC at idle 60 degrees on 80 degree day
Driving it gets down to 50 degrees
I noticed the high side line gets hot but the low side line doesn't even get as cold as before. Actually only gets cool not cold enough for condensation to form on it.
Suggestions?

Just checked AllData and they dont have operational pressures listed,
What year is your car? capacity is 32oz for 99-02 03-04 is 28oz
Did you add oil?
I'm also based in hawaii and completely forgot ambient temp has an effect on pressures in the system because its a non issue here haha

Those pressure readings look fine. Ambient temperature is not the only factor involved, you must consider humidity and the amount of heat exchange on account of glass, also. There's an equation you can look up for exact measurements. But, truth be told...you look to be within acceptable pressures. Normally, l like to see about 30° difference, between outside/cabin temps.
Also, if one of my A/C gauges ever called me a retard...it would be eating lead...lol.
