Which BMW M440i xDrive version do you own?
Compare the generation, year range, engine code and factory power, not the model name alone. These listed versions have 374 PS, 392 PS factory entries. Different outputs can use different turbochargers, control units and transmissions. Registration and software identification are checked before a calibration is agreed.
Open the exact engine record for the recorded ECU family, gearbox options and supporting hardware. Stage 2 values only apply to the specified configuration; unavailable estimates should not be borrowed from another engine. A newer software revision may also change the programming or unlock method.
For mobile enquiries, include the working postcode and parking arrangements. Physical upgrades and some ECU preparation require Slough workshop access. Output figures remain library estimates until supported by documented evidence for the exact setup.
Understand the hardware before choosing Stage 2
