BMW 525D E39 CUSTOMPRO REMAP

This 163hp E39 525d had already been tuned by ourselves in the past with our stage 1 software. However, since then, the owner has fitted a turbo from a 530d, so it came back to have the tune tweaked to suit. As you can see from the graph attached, the car now doesn't have quite the same pick up before 2,000rpm. However, from then on with the new turbo fitted, the car produces more power and torque.

Stock: 169hp/364nm

Stage 1 with stock turbo: 204hp/463nm

Stage 1 with 30d turbo: 214hp/519nm

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