Running rich and misfiring but still hitting 22 pounds

[jlgeclipsegsx]

Okay to start out, I didn't want to go on an audi forum site but a good friend of mine has a 97 audi a4 and he is running rich. I think you fellow dsmers would know just as much.
Aftermarket parts include:
Precision 6262 turbo.
Manual boost controller.
Greddy rs Bov.

The codes that came up:
p1196- manufactuer controlled fuel and air metering
p1426-manufacturer controlled auxiliary emission controls
p0134- 02 sensor bank 1 sensor 1

He is running 22 pounds no problem. It does misfire.
He has replaced the coilpacks spark plugs and mass airflow sensor.

I don't know shit about audi's but that looks to be o2 sensor related.

p1426-manufacturer controlled auxiliary emission controls

Being that it is such a generic dtc definition I would check what the codes means for Audi/VW since manufactures especially European ones like to have things for their make only. Also would save a lot of time if could see a data stream but that isn't always easy to get your hands on with out being at a shop, but saves a lot of guess work. Is the mis fire partial throttle, full throttle or all the time?

I would have maybe a dealer scan the car i work for a gm dealer and some cars our scanners cant even scan or it will come up with a very general code.
