    Weird limiter behavior with slip fbo ss a8 log is attached

    2016 camaro ss A8 One issues has gone another one has popped up. Around 4-5k rpm the car almost hits what seems like a limiter. Tuner has never seen it before nothing in the data to show what?s causing it and no red flags popped up other than in 5th gear during the pull we checked the data and the speedo jumps up X mph in a millisecond right before it hits the limiter and the timing gets pulled to 0. Any idea on what could possible be happening? It?s intermittent tuner did multiple WOT gear pulls 1-5 and got nothing other then the one time. I get in the car leave the shop try to do a pull and boom does it.
    In drive or in manual mode.
    Any help would be greatly appreciated

    What's happening is the transmission is requesting immediate torque to be pulled which is done via spark. I'd need to see the tune to see if something stands out. It could also be a mechanical issue.
