Hey Guys....
Took the 951 to the Dyno the other day. While I was pleasantly surprised at the power/torque it recorded, the pull(s) did bring up something else.
At WOT and full boost the thing is going waaay rich, as in off the scale rich. (See attached dyno results) Which probably also explains why I can't pass CO emissions!
Suggestions as to how to remedy this??

My bad.... the only mods I'm aware of are Autothority Stage 2 chips, Lindsey Downpipe (I think. The previous owner said he oout one on but I haven't been deep enough into the engine to confirm) and a Lindsey Boost Enhancer.
FWIW, the car went passed emissions 2 yrs ago in exactly the same setup without an issue. This year however not the case :-(

Is it possible that an oxygen sensor is at fault? Pull the O2 connector apart and then run it again. My N/A was running like crap until I took the O2 sensor out of the mix and then It was fine. A quick thing to check. Good luck.

So other an the O2 sensor, any other thoughts/suggestions? Is there a way to check the 02 Sensor without replacing it? And the car runs great. If I wasn't trying to pass emissions I wouldn't know there is/was a problem.
