Try browsing the Performance threads. Quite a bit of info here...

LSD to keep all that power on the asphalt.
This is the best answer to the question OP.
But as the others above me have stated, adding lightweight wheels and grippy summer tires with an LSD will make a huge improvement in how the car handles and feels without actually adding any power.
From the factory there really isn't much you can do to improve power. BMW did a really great job with the M54 motor.
While it doesn't technically add horsepower, a shorter differential gear ratio (3.38 is most recommended) increases torque at the wheels and is probably the most impactful performance mod you can do short of FI. Furthermore, a used, open diff is cheap ($200) and pretty easy to install. Make sure you change both diffs if it's AWD.
