I did not pay attention to the readings, I was only going by amount of refrigerant.
It's a 100% must know what your operating pressures are, IMO.
In general, if someone else is charging the system. Ask them to write them down or, better yet. Observe what they are doing yourself and write it down.

It could’ve taken the full amount, but I wanted to make sure I didn’t put too much in. That temp is with the truck sitting in the drive.
It's a little low, then, which might be a factor as far as center vent temperatures (CVT's) go. Also, the truck sitting stationary in the driveway will tend to drive-up CVT's and pressures because of the lack of airflow through the condenser. Most pros charge to the maximum specified amount. You will always have a little refrigerant remaining in the MGS and hoses (or in the hoses of an RRR machine), unless you channel that back into the low-side service port. Home mechanics usually forget to do that. So even if you fill a system to the maximum amount, you will still be slightly under the maximum charge.

Now that I have got the system working, and quite sure I do not have a leak, I am happy with the results. I have an appointment to have it evacuated and recharged by my local ac guy just for assurance that all is as it should be.
