Its a really nice linear mapping and we think its perfect for road course duty. Our local beta car here (@farbmw) has been to the Canadian Motorsports Park and both him and instructors had great things to say about the tune that was on the car at that time. It was putting down quite a bit less torque than our last Stage 1 revision which we're referring to a street map. Its quite a bit more torquey and great for street duty/fun.

Indeed, that road course map sounds pretty ideal. Most notably, the linear power output.
Have you guys been able to achieve something similar to this (991.2, also a 3.0L twin-turbo):
This appears to be the holy grail of FI-engine linearity. It's effin beautiful.
