Overrun fuelcut will not work well with a TPS like that, when you release the throttle to the idle position the ecu will cut all fuel until you reach the fuelresume rpm. I suggest that you set the overrun_fuelcut and overrun_fuelresume to 25500rpm. You can also choose to keep the fuelcut and make sure that the idle switch is only activated at idle, it must disengage as soon as you even think about touching the throttle. I have been through this a lot as the old CIS Audis have a switch like this that control the overrun fuelcut. The car get very jerky as soon as the switch was not perfectly tuned.
