You should look at a torque/hp graph of the N54.

Are we driving the same car? The car just falls flat on its face above 6K and cliff of torque is responsible.
The last time I checked HP is a function of Torque...without torque there is no HP.
Here is a stock N54 dyno chart...look at what happens after 5K, torque and HP dropoff
