If P-rad is truly WHP... I would like to see who else wants to argue the shift points here. Just like an N54, past 6K rpms... your power is dropping and you will shift around there. Once again, a function of small turbos.
The useless flywheel HP numbers match BMWs charts but the reality is slowly coming out.
