The management system uses full time wideband lambda monitoring. The only way you'd run lean and not know it from codes is if the tune has been written very poorly by the author.

Correct.
What codes do you have now?

I dont have any codes now due to the cat monitor being off but before it was just about emissions and how the cat wasn't doing anything
