How Practical would it be to...

[S10xGN]

...write a chip routine that alters timing according to TPS value? I would think one could run more timing during low TPS (as in cruise) then under acceleration (higher TPS), the timing falls back to a 'saner' value? I imagine it would be kind of like JayC's variable timing only tied to TPS instead of boost, and not require the harness.

Or is this the way it comes from the factory?

Basically, the factory chip pretty much does that, and most of the chip burners add some timing in the low load (LV8) areas and scale it back as the load rises.
