Thermoquad low vacuum readings

As a refresh here, I'm trying to dial in the freshly rebuilt TQ 6518. Motor is a 9:1 340, cam is a Lunati 235/243 @ .050, .526/.546 lift solid.

So today I put 4 turns on the primary rod adjustment (from 2-1/2), and increased the air door spring preload from 1-1/2 turns to 2-1/2. No change in primary rod spring yet, and no jet changes. (As I said, I have .031" nozzles, and .098/.137 jets, )

Idle is still about good at 14.9
Steady cruise at 2200 and up at 15.7

The change in rods and spring preload, changed my mid-rpm light-throttle readings from 17.5 to closer to 16.5 or so. I assume this is from raising the rods, and I probably still need to jet up from .098 to .101 (or .104 ???)

Here's my question, the WOT reading was 12 to 12.5 which I was fine with. But now I'm quite a bit richer somewhere around 10-10.5.
IS THIS WOT A/F CHANGE LIKELY FROM THE SLIGHTLY RICHER PRIMARIES, OR FROM THE AIR DOOR ADJUSTMENT???? Or both??
