    Post the tune file and a datalog when you can. That will help us identify any issues and point you in the right direction.

    I had no trouble making a 5.3 rock crawler idle without a VSS because it's using a TH350. It idles at 700rpm.
    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.
