540i m60b40 running rich

Ok so my car is running rich and need a little help finding the culprit.

Here's a list of things I've done already as part of other maintenance.
-replaced fuel filters
-replace o2 sensors
-intake manifold gaskets all around
-ccv plate replaced with vacuum caps
-fuel injectors serviced and new orings
-running dudmd chip

What else is there?
Thanks guys!
