Charged the AC but not getting cold enough temps according to the book specs. Done everything right I think, pretty well versed on the process. Throwing my hands in the air now.
Unless you're doing that in an air-conditioned garage, that high side looks pretty low to me. Even ignoring the FSM which seems to have very high targets for high pressure, standard R134a pressure charts want to see in in the range of 225-250 (if it was only 85 out when you did this) to 275-300 (if it was 95 out), and over 300psi if it was over 100 degrees.
I agree. High side looks low according to book numbers. Yes it’s an air conditioned garage but ambient temp about 80-85 at that time.
Are you charging by weight because I went that route initially and wound up adding an additional 5 or 6 oz's to get my pressures correct.
I don't like the TJ FSM's pressure chart because apparently whoever wrote that chart thinks Jeeps can violate the laws of physics - R134a is R134a and the high-side pressures the FSM wants to see are way above any other reference I've ever seen. I suppose they're covering a 10 degree step instead of five, but it still trends high. Every other FSM I've seen is in line with this chart:

With that said if you're at 85 degrees ambient then I'd follow the flowchart on the next page of the FSM starting with "normal pressures but temperatures too high". Oil overfill seems unlikely unless you've used one of those combination cans with oil and R134a in it, so I'd double check the blend door control and possibly the door itself to make sure it's not mixing heated air.
After you verify that then I'd plan on getting the system evacuated, and open it up to see what's in there.
Have you had your eyes on the evap coil to confirm it's not clogged up with plant debris.
Your low side is running a little high and you high side is a little low. This could be an indicator of a weak compressor
Unknown..... Would need yo hook up the gauges and do some tests. Just wandering, did you replace the receiver/ dryer when replacing compressor?
