Found the lower limit, sweet spot and the upper limit to the grinding on the metering valve. We got about 15F cooler with this modification. Now to see if working some of the details can bring it down any more. Outlet of the evaporator is about 40F-45F when it was 85F out last night. It was at ~55F. Going in is still quite warm so the average across the evaporator is not where the Coronet it yet.
