The BMW Serie 5 E39 1995 - 2003 catalog currently lists 30 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 Serie 5 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.

Frequently asked questions

Questions about BMW Serie 5 E39 1995 - 2003 tuning

How do I choose the correct Serie 5 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.

The figures are reference values for the listed configuration. Final results can vary with fuel quality, vehicle condition, hardware, software version and test conditions.
