    I know there are tunes out there for the 6.2 and 8 speed, but what about the 8 speed with the 5.3...???

    Doesn't matter what engine it's still the same trans.

    I've Talked with most all "tuner" companies and they tell me they don't support the 5.3 with the 8 speed yet...

    I am assuming it's a 17 right? More of an issue that no one has broken a 17 yet

    Mine is a '16 that I purchased in September of this year. Most of them told me to check back early next year and they might have it ready for me...

    Yea still don't know how it's possible
    Seems odd since the 5.3 and the 8spd are not new and they don't share a computer

    Anyone with this setup have any luck with a tuner or custom tune yet? If so, which one did you use? Thanks

    Yes you can tune the 8 speed. But it requires you sending in your PCM for unlocking so you have to wait a couple weeks. It also cost extra - $250 the last I saw.

    We can absolutely tune the engine and transmission on 2016 5.3 8 speed. Like some have mentioned it is the 2017 8 speeds that are engine only tuning. 2017 6 speeds we can tune engine and transmission.
