Your bike is a Drive by Wire bike ie: has no throttle cable. HD calles the handle bar throttle a TGS. That stands for Twist Grip Sensor. Since the throttle blade also has a sensor that is called TPS for Throttle Position Sensor. As Bob stated the tps will run 2 - 5% as the ECM is controling the blade position to control idle speed. If it closed the blade your bike would not run. It seems your tuner is a little behind the times and not up on the DBW bikes. For a cable throttle your tuner would be correct.
