Audi A6 C6 2004 - 2008 chiptuning
The Audi A6 C6 2004 - 2008 catalog currently lists 26 supported engines. Select the exact engine by its designation and original power output to open the most specific tuning result page.
Engine selection is important because vehicles from the same A6 generation can use different displacement, fuel type, turbocharger, ECU and factory calibration. The available Stage 1 and Stage 2 figures are therefore assigned to the engine configuration rather than applied broadly to the complete model range.

How do I choose the correct A6 engine?+
Compare the engine designation, fuel type and original PS output with the vehicle documents or ECU information. Contact ABG Performance when two versions appear similar.
Why can engines from the same generation have different gains?+
Different engines can use different turbochargers, injectors, ECUs, factory limits and hardware. Their safe tuning potential is therefore not identical.
Are the listed performance values guaranteed?+
The figures are reference values for the listed configuration. Final results can vary with fuel quality, vehicle condition, hardware, software version and test conditions.
