FMU - Fuel Management Unit

Raises fuel pressure based on boost pressure at a higher rate than stock regulator.

It's a 'band-aid' for too small injectors.

Makes sense because the car has 550cc injectors now. So there’s no purpose for me needing it.
does the car have a custom tune now for the supercharger and new injectors?

Clarification, in both pictures, the FMU is circled.
In the 2nd picture, the catch can is blue assembly mounted to firewall (Not circled).
