John, according to my chart at around 90 degrees your high side should be
closer to 300 psi.  I had my '84 charged up to 300 psi on the high side at 86
degrees last night and I got 52 degrees from the register above my head after
only a couple minutes of driving.  Hope this helps.

Thanks,
Ken Wilford
