I’ll admit that I’m not familiar with KW hvac box . But if heater core and evaporator are in the same box, and use one fan and blending doors, first thing I’ll do is to stop the coolant flow thru heater core and test again. Let stabilize and write numbers . Than put a good size shop fan in front of condenser and write numbers again.
This test will give you fairly clear picture what’s going on .
Let’s see and we’ll go from there.

The valve was already off for the test in the first post. It is a combined box with blend door and bypass door. I checked all the doors for range of motion while I had it apart cleaning. I'm not sure how a shop fan can out do the rad fan on lock at 1400 but I'll try it later this weekend.

Yes, it along with the cabin filter, heater core, condenser core, CAC & radiator while I was in the mood.
