Correct.. For my car with my mods, it is almost spot on. As you continue to change more of the engine however, supposedly commanded vs. actual can deviate more and more.. I have heard stories from friends/coworkers who tune and see numbers on their wideband that differ from their commanded.

What are your current mods?
