If your sitting at 3000 rpms on the highway in cruise control and hit the button nothing happens because the ecu knows you're at your desired speed so it adds no throttle.
Sit in your driveway and hold the revs at 3000 rpms and hit the button. You will see a big rise in the rpms. The sport button changes the amount of fuel the engine sees vs the throttle position.
Wrong. If you are truly "crusing at 3000 rpm" it will do nothing. Try setting the Cruise Control on a level highway ... wait for the car to get to speed and try the button, it will do nothing (I've done it and reported it elsewhere here).
If the car ISN'T up to an "actual crusing speed (steady state)," it WILL lurch forward.
It DOES NOT apply more gas at the same throttle position, it just SPEEDS UP THE REACTION TO A CHANGE IN THROTTLE. (And, of course, makes the steering stiffer.)
Agreed- I have to be on the pedal (with slight application or better) to feel the bump in response. slowing down, coasting, or crusing, there is no difference in throttle feel...
It is felt best at 3000-3500 rpm when accelerating.
I remember letting a lady friend of mine drive my beast, and i pushed the button while she jaunted down the road.
