Thanks in advanced.

Yes, pretty much any mods you make, inake/exhaust/engine-wise, you should reset the ECU in this way, and allow the computer to adjust to the new airflow. Drive it hard, and it will adapt to a more aggressive driving style. I've also noticed these cars are very temperature sensitive, so driving during the cold (usually at night time here compared to in the day time when it is hot out) makes a pretty notable difference in how fast the car performs/feels.
