Fine Tuning Movie at IGN

Yesterday IGN featured a visual tuning movie, today check out the Performance Tuning movie with commentary from a Need for Speed Underground 2 producer. Movie shows several tuning possibilities and what's most interesting is that you can tune your car while you're driving on a test track. All the changes are immediatly applied to the car so you can find the best settings faster than anywhere.
