egr, evap, map/baro, etc can go

Do you have emissions testing up in Verona? If so then in my experience there is not much that you can take off without screwing yourself for testing. I capped off and removed my egr but left the solenoid valve, tricked the egr temperature sensor with a resistor, and used a o2 simulator in place of the secondary o2 sensor. I am throwing no codes but the ecu will not complete its readiness checks...so I fail emissions.

Unless my car magically completes it readiness checks (I have already been through the factory proceedure to no avail) the car is getting registered in unincorporated Wisconsin.

Matt: Did you remove all the items you have listed above, and if so how are you passing emissions?
