Our Stage 1 tuning file takes the BMW X4 M40i 360bhp from 360 bhp and 500 Nm to 400 bhp and 580 Nm – that's +40 bhp (11%) and +80 Nm more. The remap file is written by a calibrator for your exact software on the Bosch MG1CS003 / Bosch MEVD17.2.G / Bosch MG1CS201 and returned through the portal, normally within 5–15 minutes. Solutions such as DTC Removal, Pop & Bang Crackle map, START/STOP OFF, Vmax can go into the same file.
Who is this remap for?
On a turbo petrol, a remap sharpens throttle response and pulls harder through the mid-range. For the best result we recommend running it on super unleaded (97–99 RON). 360 → 400 bhp equals roughly 268 → 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.
