Long ago Nissan 350Z appeared and really captured minds of people in race course. Some of my colleagues own this car. They tuned the car for better performance. Changes to the 350z continue with a high improvement of the car's power, achieved only by optimizing and remapping mapping than the previous model. 20 additional horses were obtained in this way, in addition to redesigning the intake manifold. Many mechanical components have been lightened by using lighter materials. In addition, the electronically controlled exhaust valve timing has been revised, as well as the distribution chain. But I believe that even after tuning will Nissan 350Z is better.
