if the tps was reset with all new parts installed, think they possibly made a mistake somewhere.

I have an '07 with the race ecm, k&n and a Micron system. I've experienced the same problem you're having. Turn your idle down a bit at a time and try the bike...it's odd, but if your idle is set too high, it'll cause the engine to keep revving for a few seconds after you let off the throttle.
