    2010 silverado beta verison v8 to v4 mode

    I have a 2010 silverado, i am using the beta version to tune it. i shut off the displacement on demand and drove it for a day or two. i tried to turn it back on and it says enabled but does not actually go to v4 mode or show it on the dash indicator. HPtuner shows its enabled. anyone have a clue on this? i did a write entire calibration also.

    what does it do when you flash the stock file back to the pcm?
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Dont forget the link between dod and cot... Cot cannot be disabled if you wan't dod to be enabled.

    rather than disable COT completely could you not just basically zero out the tables...
