Frequently asked questions

Put simply, the output increase is achieved by adjusting the quantity of fuel injected and the ignition time. Our performance tuning box picks up the control unit’s data, optimizes it and then sends the modified values to the diesel pump. The adustments are controlled via microprocessors in the interior of the box.

Fuel consumption is reduced in the vast majority of cases provided that the original driving style is maintained. To attain a further reduction in fuel consumption, we recommend you fit a sport air filter. Doing this, you also give your vehicle “a bit more air”. The exhaust gas levels of the optimized vehicle do not change.

No. Only in the case of poorly fine-tuned electronics can increased particulate emissions arise. This cannot happen with our electronics.

The performance tuning offered by us is designed for a torque and maximum output boost in the lower and middle speed ranges. Nevertheless, maximum speed is increased in practically all vehicles, since the torque is also increased here. The increase amounts to approx. 5-10 km/h depending on the vehicle.

No. But the output can naturally be measured, e.g. on the test stand. It can’t, however, be read from the electronics, with a diagnostic instrument.
