2. the engine likely allows for overboost in certain scenarios.. eg full throttle acceleration through the RPM band where additional torque wont be a shock to the engine componets but rather a smooth build as the engine spins up

3. they meant to say 5500-6500

Think of BMW specs sheets as marketing double talk... "BMW can confirm that the motor will be making AT LEAST xxx"

Yeah - My guess is #3.
