    2019/2020 5.3 trucks ecm tcm unlock!!!! Any updates at all????

    Guys all I see is really old post about this. Do we have any new news if we are going to be able to tune the 19 and 20 5.3 trucks??? I love my Sierra but man it could use some help on the trans and throttle response.

    Any info is much appreciated!! I almost feel like all hope and efforts have been abandoned!!!!

    Currently we have no eta for this application, sorry.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Thank you for the response sir! May I ask if it?s still trying to be cracked or not worth the effort at this point.
