BMW 520D E61 CUSTOMPRO STAGE 1 ECU TUNE

BMW 520D E61 CUSTOMPRO STAGE 1 ECU TUNE

E61 BMW 520D in for a CustomPro ecu tune. This vehicle did produce quite a bit less than the factory figures suggested, which meant that the peak figures on our tune were also lower than expected. However, as you can see from the graph attached, we still saw some good gains. This vehicle saw smooth and consistent increases throughout the rev range in typical BMW fashion, which is the main thing. Despite the numbers being lower than we would have liked, the increases over the stock software are the important thing here.

Before: 159hp/334nm

After: 188hp/410nm

Of course using PPE on the car and sticking to social distancing guidelines
