TPS = 15% @ idle
TPS = 80% @ WOT
LOD = 8-13% @ DFCO (depending on RPM)
LOD = 80% @ WOT (any RPM)

I have a theory about adjusting my TPS to lower this value, hoping that the ECU/TCU will upshift earlier at higher throttle openings, or that it will shift at the min speed required despite having a higher throttle opening.

In theory all you would need to do is create a small (metered) vacuum leak. Your throttle would be more closed at the same load to maintain the same MAF/o2 sensor readings. Not sure what the trans goes by as far as downshift logic goes, but if it goes by throttle plate angle, that would do it. If it goes by algorithms based off multiple sensor readings, it would't work.
