Target idle runaway - P59 SD

I believe that has been discussed before. Target idle adds 125rpm after 40 seconds idling.
Demanding 600. Starts. Comes to idle. Adds 125 across the board. Changing idle through scanner follows as commanded.

2004 P59 Silverado 1-bar SD RT

Was there ever a solution?

Tune and log attached.

It may be completely irrelevant but why does it not have any manifold vacuum? I've done big giant solid roller cam motors that made more vacuum than this thing.
