My previous XB9 had the race kit and the airbox top cover from an 08 bike (With the cutouts in it). My current XB9 has the Race ECM, Drummer SS muffler, K&N and American Sport Bike open airbox kit. I remember by previous bike being a bit snappier with the throttle. How do these two options compare? (The American Sport Bike open airbox vs a 2007+ top cover)

More probably a slight difference in the ECM mapping.
If you look at the throttle body, butterfly diameter, vs. the incoming air on the 07, I'd say that the incoming air is plenty enough to keep the throttle body filled with air.

I should have pointed out that my XB9 is an 05. Is it possible that the extra flow from the open air kit would have adverse effects?
