    2013 Auto CTS-V Not Rev Matching After Tune.

    After doing a pulley swap and dyno tune, the car will not rev match on the downshift. Havent found anyone with the problem. About to load the stock tune back onto the car to see if it fixes it then just go back through the tune and flash it one step at a time. Just wondering if anyone else has seen this before.

    Somebody either turned off torque management completely or turned off closed throttle downshift torque management.
