How stupid is this
BMW pretends they are unaware of their new software detuning our cars.
So it takes an aftermarket tuner to fix it
BMW sucks.

Lag Fix
This parameter enables a “fix” for those owners who have been undated with an unfortunate software version at the dealership. This version has been shown to reduce turbo boost response below 4000rpm. When this parameter is enabled, an alternate duty cycle map is activated in the PROcede- one specifically designed to eliminate the lag caused by the aforementioned software update. Do not activate this feature unless you have this lag-inducing software version. Doing so may result in a trouble code/limp mode.
