All that would have to be done with an intake is see the engine is lean stock and slightly larger maf hole to richen it up , this would keep the engine safe , make more power...

Yes I have had about 10 2012 on my dyno they were all lean

1) Why would the front O2 not be used during WOT? I have never seen my car go open loop @ WOT.

2) I am getting a steady 12.4~12.5 (commanded and actual) AFR @ WOT.

Could this be attributed to PCM calibration differences or...?
