While I'm sure the X5M guys will tell you about every single internal engine component that differs between the two engines (and there are a few, admittedly), they are essentially very similar to one another. The X5M50i is just heavily "detuned" from the factory.

Agree. Essentially, you can get a tune from BMW from the start or a 3rd party, later. Either way, max HP should be the same. 95% (or more) or the wo engines are identical.
