Tuningfile is an electronic performance enhancement via software optimization. The result is an increase in torque and engine performance. Depending on the manufacturer we usually achieve with Stage1 a 30% increase in output and a 15% increase in fuel consumption. Optionally it is also possible to legalise our performance increase. Without registration/typification the vehicle license expires in many countries. If no part certificate is available, the customer is obliged to register the performance increase by individual acceptance.
