    Throttle Position Sensor getting clipped at 50 in Scanner playback

    I did a test run, saw the TPS value while recording up above 75% a couple of times, but, when I get back and zoom in, the value is cut off at a max of 50% for the entire run. You can see the table tops in the graph.

    What is causing this?

    You are logging 2 TPS channels, remove the non SAE channel.

    Then maybe try it again.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
