HAHA Bman- what did you do?
I got my C4 with the 930 motor to pass by doing the following-
1 install cat
2 adjust the fuel mixture to ALMOST lean misfire
3 had MSD 6AL with blaster coil to fire the leaner mixture
4 bombarded the fuel mixture with dry gas (alcohol) on a low tank of gas.

In the end the car didnt drive very well to the test but when it was done I took the cat off, fattened up the mixture and drove worry free for the next 2 years.
If I could get a CIS motor to pass in the C4's body that was meant to have sequential injection with twin plug, anyone can do it.
