All written for the xDrive 28i specifically.
What STAGE 2 involves
STAGE 2 assumes the supporting hardware is already fitted and in good order. We check what is on the car before quoting, because the file is written around that specific combination rather than pulled off a shelf.
It takes most of a day. We keep your original file, so it can go back to standard at any point. Figures here are for a healthy xDrive 28i, and we check the car over before writing to it.
See the full xDrive 28i page for every file and figure, the other engines on this X3, or all BMW remapping.
