    I've held back on the intune tuner myself for the same reason, I was a Ford dealer tech and I know we could see a lot more than people thought we could. I was told by diablo reps they leave no water marks but, I know GM better than that and figured the data logs were deeper than tune guidlines. Your post proves it; Any links to the range module you sited? I see your link above, but on the link you post the only thing I can see that module doing is increasing the use of AFM. I want to shut it off, my dealer said they could not when I asked.

    I've never had an issue with getting warranty work done on my truck and I leave my tune on. But as I've said before we have a great relationship with our dealership

    This thread is about the AFM shut off capabilities of the Range module.

    The techs will not check for a tune or check the log files unless GM requests it and GM will only request it for major engine work such as replacement, rebuild, etc. I cannot see them questioning the tune of a water pump goes out, or a throttle body requires replacement, etc. only because it would be hard to document how a tune could cause those types of failures.

    Bose thinks they make speakers, Ever since I heard bose car audio speakers, they were one of the first things to get replaced in the vehicle.

    My Bose speakers sound awesome! You guys with low oil pressure readings, have a look at the oil sending unit, and the screen in the manifold. My sending unit was bad, and the screen clogged. I replaced those and my truck runs like a champ. Back on topic, the Diablosport Intune has the capablilty of turning off DOD. I leave mine on. This little handheld is truly a nice product.

    I tried manual shift mode on my 2011 and it still went into 4cyl AFM mode, I also tried tow/haul hoping that would lock it out but no luck.

    Try it again. Put it in manual 5 and the AFM should not go on. This is the first I have heard where a truck is not operating properly in manual mode.

    M5 the AFM should not turn on, M6 it will.
