Xfi 2.0 question on lt1

Got it...
Kinda what I suspected...
Is it tied physically to the throttle shaft or just lean/rich the mixture via controlled air leak?...

A friend resto-modded his street car with an LS-X and it hunts at idle...
Doesn't really seem to run like I would have expected a computer controlled car to run.
Seems rich all the time too...

Sorry for the questions but I really don't know anything about modern fuel injection.
Trying to learn.

If it ain't got pills or jets I'm lost!...
