OK, I've gotten a better handle on this (better doesn't mean a whole
lot in my case, though).

Here are my stats:

Suction line - 63 psi, line temp is 53.5 deg F
Liquid line - 215 psi, line temp is 163 deg F.
Ambient air at bottom of condenser is 81 deg. F.

(This is after adding about 2 lbs of R22.)
I would stop adding refrigerant here. When
outdoor temps get into the upper 90's, the high
side pressure will be 250 or higher. That liquid
line temp is really high, especially for a
relatively new unit. I'd check for dirt in the
condenser. I have to wash crud out almost every
year with a highly focused water spray, and it
makes a huge difference in performance. (I have a
pair of 33 year old Bryant ultra-cheapo units that
I'm babying along until one blows the big one,
which can't be long off.)
What is the outlet air temperature from the
evaporator?
