    From a stop in first gear...off the brake and gas pedal down...tachs up with tires spinning then engine cuts out for about a half second ....
    comes back on full. Thought I was maybe hitting the rev limiter in manual mode, but if I leave from a stop in auto in first gear it still cuts out before shifting into second. Its hard to watch the tach but the trans should shift out to second before any kind of limit is hit....This happens going in a straight line, so I don't think ESC is a factor. I turned ESC FULL OFF and the engine still does this cutting out. No problems second gear and up. I have watched vids of hellcats spinning tires through the gears and never seen this happen. ????

    What happens from a 10mph roll when you punch it?

    Is it full of gas? At least not low enough to fuel starve by pulling all the liquid to the back of the tanks sucking the inlets dry? Just one cheap check.

    always plenty of fuel....has done it from a roll in first gear. I am going to try second gear launches and see if it cuts out the same...

    My car did the same thing in first gear and I have a M6, thought I got the r's up to high and hit the rev limiter but it has not done it since but have not taken up that high again.

    Mine has never cut out. Clogged fuel filter or something clogging the fuel line that restricts flow?

    Traction control not turned off all the way?
    Look at the srt screen make sure traction said off.

    I know in my situation the traction control was not all the way off, it was in sport mode. I have the dealer also looking into it to see what they think.
