    Default 2011 Tahoe E38 T43 pulls throttle at ~6000RPM

    Dynoing a 2011 Tahoe I hit a wall where it would only rev to ~6000 RPM.
    It was going to 6500 where the rev limit is set prior to adding timing which increased power.
    I tested that it wasn't a MPH limiter and it isn't.
    Cals and log are attached, what am I missing?
    Thanks
