CIS automatically maxes out fuel delivery upon full boost.
"That's all there is.....there ain't no more"
So your air HAS changed once it passes the metering and through the turbo

Beyond this, controlling the AFR is dependent:
On air density via Intercooler cooling
The ultimate amount of fuel added under full boost -managed/added by the WUR, with additional added by the IA fuel head if necessary.
