Tim, I had initially overcharged it, thinking it was low on freon (i.e. R134a to make tcar happy). The current charge is 40/180.
tcar, I vacuumed it down after overcharging with the cheap stuff. I vacuumed down to 30 in HG, and held it for 30 min. It's a pretty powerful pump, my dad made it out of a refridgerator compressor and some sort of motor. I then charged to the current 40/180.
