I met up with Vadim today and we took the car in. I wasn't sure what to expect but I'm totally happy with the results. For the first few miles the car was bumping redline and shifting hard into 2nd (ESP blinking and all), but after a few miles it's back to normal.
It's a bit deeper at topend, and it's only noticeable past 4k rpm. This car should have come like this from the factory.
As for the performance gains, I'm not sure if it's revving quicker at topend or the sound difference is making it feel quicker, but I'm happy with the results. It got even louder about an hour later.
Vadim, thanks for your time, and both your cars are simply awesome.
