Err so you're running bandaids and wondering why the AFR's aren't on target
I know the NB rail operates at 4bar fuel pressure instead of 3bar, maybe the FMU isn't compensating enough.
Better option is to upgrade ECU and injectors to something standalone. Stock fuel pump is fine for like 200-250 hp or nearabouts..
