Non-binding guide values. Stock figures are manufacturer data; figures after optimisation are experience from comparable vehicles – not a guaranteed property. The actual gain depends on the condition of the individual vehicle, fuel quality, production tolerances and fitted components. A power increase must be registered under § 19 (2) StVZO in Germany. Modifications to emission control systems are not offered.
