Vintage Air System not too cool????!!!!

I had a malfunctioning heater valve with my Gen IV with electronic controls. I switched to a manual valve and now it will freeze me out at 100F...and I have a convertible.

The Vintage Air tech also said the line pressures are fussy for proper operation and to avoid annoying harmonics. He gave me different numbers from the original instructions, but I can't recall what they were.
