Honest question... can you prove that? There's a lot of speculation on these forums, but no one has actually proven that their car was making lower power before their first service. I'm not choosing sides, I just want someone to prove it, one way or the other.
I don't need to, that's beauty about the search function in this forum.

Yeah, but for the M5 it was pretty much agreed that it's BS on that theory.

I don't own M4 so don't visit there much but I doubt the de-tune theory applies there as well.
