Yes, thanks that explains why the cylinder pressure is higher at sea level for the same boost and thanks to JoefromPa as well since it's what you were saying.

Do you know if this compensation with lowering boost a sea level was done for the N54 as well or if it's limited to more highly tuned FI cars where margins is a concern?
