Did you do rear air ?

No rear air, Greg, and it's a very large interior space. I finally stopped at an auto parts store yesterday and bought a can of Sub-Zero refrigerant with a gauge. It showed slightly less than 30psi on the low side, so I bumped it up to 40. They don't recommend more than 50 so I have a little more I could add. It helped quite a bit so I may boost it up a few more psi. I think the o-ring in the low pressure fitting at the compressor is still not the right one. There was a tiny amount of oil there like it has a very slow leak. The refrigerant I bought says it seals leaks in o-rings, gaskets and hoses, so we'll see if it works as advertised.

It's been like "whack-a-mole" Dale. The expensive Aeromotive regulator I installed doesn't seem to want to work very well when it gets hot. This evening as we were headed out to a restaurant, the car died as I pulled into the parking lot. I popped the hood and checked the fuel pressure and it was over 10psi when it should have been 6.5psi. I broke out the toolkit and reset it to 6.5 but I have no idea why it would be changing like that. I have one of those fancy schmancy gauges you can manually vent to get an accurate reading under different temperature conditions, so I know the pressure was what I was seeing. Also seem to be still having issues with the torque converter clutch solenoid. Also heat related. I did get to talk to a Painless rep at the show today and he gave me the name and number of a guru that may be able to give me some tips on programming. It would be great if the issue went away with a different calibration, but if the solenoid is acting up when the transmission gets up to operating temperature, a new cal file may not be what it needs. I see more revisions in my future.

That's very true. I did turn the fans on and put a paper towel up to the front of the condenser and it held it there with no problem. However as the whole system heats up, I'm sure the condenser becomes much less effective. I noticed at the show today, one of the vendors was selling a prepackaged core support / radiator / condenser. The condenser was much smaller than mine and only covered maybe 60% of the finned radiator surface. I need to stop by and pick their brains on just why they make it that way. As I mentioned earlier, adding refrigerant helped a lot. And if more is better, too much oughta be just right.
Here's a few photos from the show today. I haven't heard an official count, but I'd estimate close to 2000 cars if you count all the drag cars and show cars in the vendor areas. We had plenty of room to put up our canopy and boy did we ever need it. Heat index near 110 and only a gentle breeze. We left right after the 50/50 drawing at 4pm and made a mile for the air conditioned motel.
