I just returned from an emission testing center very disappointed after my VX failed the emissions testing miserably. The following diagnostic trouble codes were given:

-Low voltage O2 sensor (Bank 1 and Bank 2)
-Fuel and Air Metering Code: System too Lean (Bank 1 and Bank 2)

The mechanic says that supercharged vehicles with aftermarket exhaust systems usually don't pass emissions testing, especially if the O2 sensors and the Mass Airflow Sensors are removed. I did not install my SC personally, but is it customary to remove these things? I really don't want to have to
RE-modify my VX back to stock, just so I can pass the $20 emisisons test.

Any suggestions?
