[200q20v] Vent Problem

Can boost runs reduce available vacuum sufficiently the climate controls 
that rely on vacuum to hold/create settings lose their  power 
briefly?  I've noticed during colder temperatures that if I really jump on 
it (like a 3rd gear run up a long, steep hill with a redline shift to 4th 
and still pulling),   my climate control seem to switch from producing hot 
air to producing cool or even cold.  Reminds me of the "old" days when 
vacuum-operated windshield wipers would stop midswing during acceleration.
