There is definitely something going on when the car is in sport or sport+ mode. If you get it under some load and make full boost, even if you shift at like 3500 rpm, there is a "brrraappp" out the exhaust on the shift that isn't present in the default mode. It sounds a bit similar to what the DCT cars sound like on a shift. I'm hoping that it is a big timing dump that is happening in conjunction with the wastegates moving to a much more aggressive position....both which work together to keep the turbos spooled up during the shift.

Anecdotally, I noticed NO performance degradation on the shift running down the straightaway at SPA against the DCT cars.

I eagerly await getting mine back so I can do more testing and logging. If this is actually the case, it is another huge win for the 6MT drivetrain along with better fuel econ in the US, and better reliability.
