The only thing I've heard of is using a small piece of rubber and a zip tie behind the pedal to eat up a bit of slack. It'll change the resting height of your pedal, though. If you push the pedal all the way to the flyer floor and the throttle plates go vertical, all is well.
The best way to check is with a scanner and a watch the TPS output at key on, engine off. If it gets to full throttle percentage, no need to adjust.
