    2014 gmc 6.2 accelerator pedal position off.

    So, I've been tuning on my truck for a few days now. And I just discovered that my pedal position starts at 18% (w/out touching it) and only gets to 83% when pushing it to the floor. I tried a new pedal, same result. Anyone ever experience this, and how do I fix it?

    The TPS channel will only read to 83 or 84%, that is not a problem.

    Theses are also drive by wire, so the throttle is always open no matter what. There is no IAC valve, the blade has to be open to let it run.

    You can log other throttle position channels to see if the blade is going to 100%.
    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.

    There is also a difference between the generic "(SAE)" channels and the GM-specific channels.
