BMW 4 serie 420d 184bhp tuning file

With a bespoke remap the BMW 4 serie 420d 184bhp gains +36 bhp and +60 Nm, rising from 184 bhp / 380 Nm to 220 bhp / 440 Nm (20% more power). We build each tuning file around the software number of your read on the Bosch EDC17C50 / Bosch MD1 / Bosch EDC17C41, 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. 184 → 220 bhp equals roughly 137 → 164 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.
