Power outputs

I noticed my dad and I have the same engines. He has a '08 X5 3.0si and I have a '06 330xi both using the N52B30 engine however the only difference is he has more torque and more horsepower but saw on wikipedia he has 200kW power output and I have the 190kW power output. So what decides the power output? Wikipedia says "output changes result from the omission of the variable resonance system, dual plenum intake runner system, and the variable back pressure muffler"

So what's it mean? is it just those bolt ons (muffler, intake, and resonances)? Or is it ECU settings?
