I had a 96 Z28 for a short time. It never cooled well. Not sure about how similar they are. You might be doing the best the system, will do. Way too many pages of posts to read them all. What I have read is your pressures did not seem that far off.
Tim, yes this is a long thread and I should probably summarize it soon. Other than the evaporator freezing on drives longer than 1 hour, my black Trans Am's ac always cooled very well in the Florida and Texas heat. At the beginning of last summer, during my first couple of ac uses, it seemed to take just a little longer for cold air to come out of the vents. After several uses, the ac seemed to be working normally and I just thought that maybe it needed a "wake up" from not using it during the cooler winter months.
At the beginning of this summer, the "wake up" was much worse. No cool air for quite a while and even then, it didn't get very cold. I started driving with a thermometer in the vent and could only get 55F temps at best. It would take a while to get down to 55F. I never measured the good working OEM vent temperatures but I would guess they were close to 40 degrees.
Even before I recovered the refrigerant several days ago, I couldn't get any cold air. Vent temps were barely lower than ambient. After running the ac for about 10 mins (doors open, fan on high) I got the vent temp down to the mid 70s. Not good.
I've been driving my wife's 2013 Honda CRV and the ac puts out cold air almost immediately after start up. I've also been driving my big, 2001 Ford F250SD crew cab diesel and it too puts out cold air almost immediately. With both of those perfectly working ac systems, I usually end up turning the blower speed down after a short while even when it's 95+F outside.
