i have a 03 6.0 and was wondering if removing the butterfly valve has any benefit and if so does this trigger a check engine light?

There is a throttle plate in the intake manifold. I don't know if removing it will trigger a check engine light, but I do know it was deleted by the time they started making 2004 models.

There isn't a butterfly valve in the exhaust like the 7.3L had.
