That being said it may be as you stated that Sport Plus setting offers a mapping speed not obtainable by a human. But again, that being said I think the result is still not ultimate performance, rather feel and control. It would be an interesting experiment to find two closely matched cars and drivers and do a rolling start test with the throttle in different modes. This can be done now with an E46 M3 as well.
Agreed that the extra Hp is BS. If sport plus does offer stepper motor control that cannot be attained otherwise, I guess that would allow the driver to be more involved due to faster response, which might or might not result in performance gains. As you are saying, we'll need to see some reviews that specifically focus on issues such as this one (I also want to see a comparison between EDC-sport and non-EDC suspension setups before deciding).
