Do you have an pics to post of that new setup? I know that A/C vent temperature is dependent on many factors, and 134A + the smaller Sanden compressor will not be as powerful as an old R12 stock compressor, but what does Vintage say should be your vent temperature? In 110 degree desert climate I wonder if 45 degrees would keep up at idle or city driving.
My stock 134A converted system is noticeably not as good at cooling as the old R12 system, so I have to run it on max cool setting more often to keep the truck cool at idle and stop and go driving. Whenever I have talked to A/C mechanics about converting the stock A6 compressor to a Sanden they have said that the Sanden was not powerful enough for the stock system, but that does not consider that the new Vintage system would be designed around the Sanden compressor.
