BMW 4 serie 425d 224bhp tuning file

With a bespoke remap the BMW 4 serie 425d 224bhp gains +46 bhp and +50 Nm, rising from 224 bhp / 450 Nm to 270 bhp / 500 Nm (21% more power). We build each tuning file around the software number of your read on the Bosch EDC17 / Bosch MD1, so nothing generic goes back into the car. Add Adblue, DPF OFF, DTC Removal, EGR OFF to the same file if needed.

Who is this remap for?

On a diesel, the bigger gain is usually in torque. Expect stronger pulling from low revs, easier overtaking and a more relaxed drive on the motorway. 224 → 270 bhp equals roughly 167 → 201 kW.

Figures are guide values from our rolling road and comparable vehicles. Results depend on the vehicle's condition, hardware and fuel quality. Remapping in the UK: let your insurer know about the modification. DPF, EGR and AdBlue solutions are supplied for off-road and motorsport use only and are not legal for use on UK roads.
