    2015 Silverado 5.3 and 6speed any help would be great

    Newbie trying to mess with this tune. I'm really kinda afraid to mess something up. Does anyone have a tune I can compare to? I've messed with transmission some and not sure I've done anything right. Truck is all stock.

    I'm new to this as well, but since we have the same truck I have a question for you to see if you see the same problem. at WOT "Commanded Throttle actual shows 100%, but Throttle position only shows 83.9% and "accelerator position" shows 85%. for the life of me I can't find where to adjust this. does yours show the same by chance?2500 to wot.hpl2500 to wot.hpl

    The TPS will only show up to 88% on the gen 4 and 5 computers.

    You can log other throttle related inputs though.
    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.
