    6l90e

    Work truck/ tow pig. Basic bolt ons should I leave transmission tune alone? I?m new to tuning I haven?t done much with the engine tune yet.

    Do it all.

    The 6L80/90e can be made to drive way better than they do if you take the time to dial it all in. It doesn't take a ton of changes to make it shift faster/cleaner and when you want it to.
    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.
