It should not be a stretch to assume BMW designed this engine to provide many miles of service to people living high in the mountain areas...

cant talk for JB1 but SSTT is not based on altitude.

In fact we tested it with the unit still on the car and it was not detected

It seems to use more of air temp and timing to get the mild boost from what I have read (split second is hush hush on the details).
Could you point me to any BMW documentation that quotes the 11 psi ? (I’m being serious not sarcastic). I have seen 11psi a lot in the forums, but not in any official documentation or Mags
