Many thanks to Chris Z, Andy W, Douglas B, Kevin S, Charles B, Wolfgang for your time and thoughts. Also Justin at Lancair.  Thanks for the refreshed understanding of what was going on here.  Right now, my airplane in the shop for upholstery down in Corpus Chrisi.  Can't wait to get it back, but in the meantime I will be editing my check list to include the dump valve cycling.  In the past, its always "just been there".  Additionally, a couple of you asked if I had pressure gauges installed on the hi and low sides.  I don't currently but will most likely entertain that idea if this becomes an ongoing issue in the future that requires more careful diagnosis and adjustment.  Thanks Again!!!
