We need to post this info from Bigtsr in our Knowledge Base as a sticky. It's too important to let it get buried. I have edited it to add how I did it because the way I did it really improved the throttle response! This possibly could improve the manuals as well since it is mainly a reprogramming of the throttle response. I don't really know how much this directly effects the CVT.

You can recalibrate the throttle yourself to eliminate flat spots or pauses in its response curve according to the post, as I am not having any problems in those areas I thought I would post the procedure here and anyone wishing to try it could post the results.
1-ignition to RUN but do not start
2-wait until all the idiot lights go out (engine light should be the only one to remain on)
3-slowly depress the gas peddle to the floor (take at least 15 seconds to gradually push it to the floor, do not waver as you push)
4-slowly release gas peddle to full up (again, take at least 15 seconds to gradually let it back up, do not waver as you let up)
5-ignition to off
6-DO NOT START IMMEDIATELY! Allow to sit for up to 1 hour, then start and check for difference in response and linearity.
