P7100 Governor Spring GSK limited rpm, affects from fueling and timing Q's

[GOT-Torque]

For the sake of discussion, if you take a truck setup with a 5k gsk that spins 5k on the line (free load, then drops some down the track) with big injectors and put really really small injectors in it, is it possible that it won't be able to spin 5k free load anymore since it doesn't have the fuel necessary to do so?

Same question related to timing. Same truck setup for 5k running lets say 30 degrees static timing. No changes other than pulling timing back to 20 or 15, wouldn't this limit rpm since the fuel will be combusting so late? Or would it still turn the rpm free load but no where near it loaded?
