    2015 gmc 5.3 wot delay

    I'm still having trouble trying to get my truck to get to wide-open throttle does anyone know what the problem might be for this ? As soon as you go wide-open throttle there is a small second delay . Can anyone point me in the right direction

    Auto-correct strikes again lol.
    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.

    Put your peak tq table back to stock, or only a little over stock.

    There are a few things you can do to change the way the truck shifts. Your peak tq table does not need to be crazy. Like yonson said. Only a little over. You can change a bunch of things up in the transmission settings. Along with Driver demanded tq settings. Be very careful here. As you will need to log and see how it adapts.
