I've never heard of this until now. As much as I would love to have a button to close the waste-gates shut, I don't think that's the case. How can we confirm this? I'm thinking if this is true, the common waste-gate rattle would be eliminated when M mode is enabled, correct? Or maybe a clicking close sound coming from the turbochargers when the button is pressed?
Please read the link in the OP from BMW. They talk about how it works and how it apples to both the 1M and the M5...

Guys, why can't you read this stuff before trying to disprove how it works??
