X6 40d remap questions

How much bhp does a BMW X6 xDrive40d remap add?

Is the X6 40d the same as the X5 40d?
Yes: the same twin-turbo B57, with the same Stage 1 result of around 400bhp and 800Nm.
Will it affect the X6’s refinement?
No. A custom map keeps the engine smooth and quiet; it just responds more strongly when you ask.
