The 2014 BMW F31 with a 2.0-litre diesel engine and xDrive was first tested on a dyno. Factory ratings are 184 hp and around 380 Nm; this particular car produced 179.5 hp and 381 Nm with its original file.

The owner wanted more power without an aggressive tune. The technician chose a moderate Stage 1 calibration, also taking into account concerns about timing-chain load on this engine. After the software adjustment, the dyno recorded 216 hp and 450 Nm.

The video states that the vehicle’s emissions equipment remained in place. The result was achieved without changing its physical configuration. Compared with the initial dyno run, the measured increase was 36.5 hp and 69 Nm.
