    Someone has to put a file into the repository for there to be one for you to look at, some vehicle just aren't in there.

    The other fact is that the 6.5 diesel isn't on the supported vehicles list from what I see.

    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.
