    I have a 2014 4x4 crewmax 5.7 reg gas tundra. Went to dealership and had the software upgrade and I swear the truck is running different. It's shifting different also. Has anyone experienced anything after doing the ECM software upgrade?

    Was the update for 3rd gens only? I had an update done on my 07 recently. Nothing noticeable at all. Even the Smart Stop. Nothing.
    CORRECTION: I see now from a earlier post that it's for 12 to 14's

    No problemo. I just read the first post concerning the flash. Looks like 12 to 14 are the ones needing reflash.
