If your using the pocketlogger software from digital tuning, your tps should read 9-10% at idle and should go up smoothly to 100% at WOT Digital Tuning TPS parameter
. I know the AFC and I think ECMlink does as well, show 0% when its closed, I don't know if they work off the idle switch or what though. I would first check that your throttle cable does not have too much tension on it keeping the throttle plate open since the tps is reading 16.7%. If you haven't alread, make sure there is nothing obstructing your gas pedal from going the full distance to the floor since you aren't reaching 100%. Then if that stuff is ok, I would check your Idle switch and see if it is screwed in too far causing the throttle to be open when it should be closed. If those things don't bring the tps down to 9 or 10%, then you might want to adjust your tps.
Also I have the MMCD software on my logger and it too reads 10.1% tps at idle.
