The F-Series 125d is a proper fast little hatchback. The 2.0d engine already has 224bhp in stock form but with a stage 1 remap of the ECU you are looking at more like 270bhp. Then with the torque boosted to 550Nm it's like driving a 3.0d. The remap transforms driveability and usually improves MPG.

We love tuning BMW's and at MoreBHP in Crewe we'll remap your 125d on our rolling road. This custom remapping allows us to calibrate the settings in the ECU to the characteristics of your particular car and your requirements. It also allows us to maximise the car's potential whilst keeping it running safe and being reliable. We aim to perfect the delivery of your 125d, making it smooth, good to drive in all scenarios and be fast.

As part of the remap we'll also adjust the Sports Displays in the I-Drive so you can keep track of the extra BHP and torque available.
