    2019 GMC Sierra Support?

    Is the support of tuning the 2019 GM trucks coming soon enough?

    I was looking for tunes the other day. I wanted to see the factory calibration for the 275/60/20 tires. Thinking about putting those on my truck when I need some tires.

    So if you have those tires and can finally read the tune, PM me

    Sorry I couldn't help, best bet is to email support.

    It's the same style computer as the ZR1. So if something did come out expect to be paying more than you want just to tune it.

    Well, same style, sort of, but completely different. Additionally it appears the 4.3 uses yet another ecm...don't hold your breath guys. Consider buying a ford.
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Which are the last confirmed GM's we have or will have access to?

    2018 Yukon, Tahoe? or 2019?

    2018 pickups obviously.

    or what? Bill can you clarify? With Beta? Without Beta?

    So now ford has the easiest ecm's for tuning? I wonder how much it will cost to have these worked on down the road when the warranty is up. Gonna have to take out a loan for repairs.

    not necessarily the easiest to tune, but rather "still accessible."

    I just bought a 2019 GMC Sierra Limited 4x4 with the 5.3L engine. This is essentially the old style body, identical, I believe to the 2018s. Is it possible to tune this?

    Maybe?

    Try reading the computer and see if it's still the E92A like the 2017-2018 model years.

    Thanks. I pick it up in a few days, and that's the first thing I intend to do.

    Just remember your warranty if you can lol. They can track that stuff on those computers.
