    Post Throttle Position Sensor Question

    So I've been doing some self-tuning and logging, but noticed on some WOT pulls (foot is solid on the floor) I'm not getting a reading of 100% throttle from either the pedal or the TPS. My pedal seems to stay around 91.4%. Is there something I'm missing or is that the way it is?

    Attached log @ 2:30 will show a good pull and you can see it tops out at 91.4% pedal, but TPS is way lower.

    The tune for the pedal is stock, so I'm not sure if that has anything to do with it or not.

    I should note, that TCS and ABS are all off.

    That threw me off too.. ~75-80% is WOT
