What a remap does for a petrol BMW 5 Series

On a petrol car the ECU controls fuelling, spark timing and any turbo boost. A remap re-calibrates those maps within safe limits, so the car responds more eagerly and pulls harder through the rev range.

How the BMW 5er E34 525i 170 compares

Among the 30 petrol 5 Series engines we have figures for, the 5er E34 525i 170 ranks 20th for power gain, 2 bhp below the 5 Series petrol average of 22 bhp.

Across our whole catalogue the average petrol remap adds 27 bhp and 51 Nm, so this engine's 20 bhp and 40 Nm sits below that benchmark.
