It is possible that that gauge needs to be recalibrated. The manual that I sent you will tell how to do it.
Have you done a log with Cypher?
That will give you the reading of the factory wide band. It is much easier to read after than trying to drive and look at the gauge.
I do remember that Sam told me that the factory ones do read 1.0 off (not sure if it was rich or lean) so take that into account.
I agree about the spoiler. Looks clean with those wheels. And if you can swing it that Zele exhaust would be SICK!
Glad you're having fun with her.
And yes, I approve.
