    2011 CTS-V wont rev past 4000rpm.

    It doesn't have to be perfect, it just needs to be done in two weeks...

    What Bill said.

    It's probably in your supercharger torque settings. Looks like you're making a little over 200 Kpa when it stops. It looks like it's shutting the blade, based on your dynamic airflow, and your boost, but your ETC% is staying at 100%. So you're either not logging the right ETC pid, or the boost solenoid is opening.

    Start by bumping your 'Boost Disable/MAP Disable' up above whatever boost you're making. Set it to 220 or 230. See if that fixes it.
