This sounds like correct functionality. Valves are only open or closed, no in-between. Tour and Stealth will have valves closed at idle, Sport will be open. As Azerlazer already said, Stealth keeps the valves closed all the time but Tour will let them open if you're driving and go close to WOT. Sport will keep them open most of the time aside from constant throttle cruising at backroad/highway speeds.
