BMW 4 serie 420d 190bhp tuning file

With a bespoke remap the BMW 4 serie 420d 190bhp gains +30 bhp and +80 Nm, rising from 190 bhp / 400 Nm to 220 bhp / 480 Nm (16% more power). We build each tuning file around the software number of your read on the Bosch MD1, so nothing generic goes back into the car. Add DPF / EGR solutions 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. 190 → 220 bhp equals roughly 142 → 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.
