What's your point?

Why do you even care if you're walking everywhere?

The point is it would be nice to maintain a flat torque curve all the way to redline so the car pulls hard all the way to redline..

BMW chose to size the turbos for low end torque. They can't support the airflow required to maintain the same boost to 7k. I don't really like it but after driving the car for two years I enjoy having the low end torque for daily driving.

My S4 has plenty of top end boost with GT28 turbos but no boost below 3600 rpms. Everything is a compromise but I'm pretty sure most people would rather have low end torque for a daily driver. That doesn't mean they still can't complain about how they miss the upper end torque.
