The customer applied after a chip tuning done elsewhere, with which he was not completely satisfied. He complained that the car starts with difficulty due to the “sticking” wheels, the car is difficult to control on the road, and turns. We redid the chip tuning and managed to achieve nice power increase results, while maintaining dynamics and a smooth and efficient start.
