I am glad your AC performance is so good...
But I couldn't help but laugh when I saw " upper New York State"....
Even doing what you did correctly on some of our 20 plus year old cars you might have needed to clean the fins on the Evaporator to get that kind of results...... as DMorrison found.. almost 50 percent blockage can hamper overall performance.
Why don't you drive your awesome cooling machine to Centerville, Texas on July 29 and join in the festivities ?
All of your food that day is on my if you do...
