    4.88 gears for one, those tires are extremely heavy and oversized for stock gearing.

    Otherwise nothing you do can really wake it up when it can't move out of it's own way. Past that read up on power enrichment settings, torque mngt and timing changes. All of this has been covered a lot by now.
    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.
