With a bespoke remap the Mercedes Benz B 250 CDI 204bhp gains +36 bhp and +80 Nm, rising from 204 bhp / 500 Nm to 240 bhp / 580 Nm (18% more power). We build each tuning file around the software number of your read on the Delphi CRD3.x, 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. 204 → 240 bhp equals roughly 152 → 179 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.
