The differences can be minimal if both programs make the same mistakes in how
they allocate time.  But not necessarily.  IE remove the airbox/cleaner from
your car, and it will run just fine if you avoid dusty/gritty environments.

Remove the airbox from your outboard boat motor and you will discover that it
will run lean and possibly fry a piston or two.

It all depends on the design decisions that were made by the two different
designers.
