Your O2 sensor, your ISV, the multifunction temperature sensor and, possibly, the reprogramming of the ECU could all contribute to rich running, I believe.

Trying to correct a rich running car-
Stock 3B although running RS2 turbo and EM and software.
In the past year or so I have replaced the coolant temp sensor in back
of head and fuel pressure regulator. I pressure tested the system
recently and the F5DPOR (I think thats correct) plugs, cap and rotor
have less than 20k miles on them.
I plan to swap in some different injectors in the next couple days.
Other than software - what else would cause rich running?
