BMW X3 xDrive M40d 326bhp tuning file

With a bespoke remap the BMW X3 xDrive M40d 326bhp gains +74 bhp and +120 Nm, rising from 326 bhp / 680 Nm to 400 bhp / 800 Nm (23% more power). We build each tuning file around the software number of your read on the Bosch MDG1_MD1CP002, so nothing generic goes back into the car. Add 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. 326 → 400 bhp equals roughly 243 → 298 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.
