Tune fixed the issues of it running lean.

We have not seen this issue with just 1 additional mod. We have seen this happen with customers running Gen 3's, Cat-back, and High Flow Cats or Headers. The Cat-back and Gen 3's have never given us an issue. I would be interested in figuring out why yours threw codes.

So are you getting any CEL's? There are other factors that could be contributing to this, but it is hard to say. Not knowing where your car started a dyno would only tell you so much. Either way, you will gain power from a tune at this point (though if you are thinking about any other engine mods I would do it before the tune).

50K + is a bit optimistic. I have spoken to K&N and they are very confident in their filters. For an air intake system they have said that 25-50k miles are the cleaning intervals that are ideal. The best thing to do is to inspect the filters and see if they need cleaning. Dirty for the K&N oiled filters isn't really a big issue. They state that the filters work better when a bit dirty. I personally clean my filters when I see build up on the wire mesh for the filter. Was typically ~20-25k miles when I lived in Los Angeles. Seems to stay cleaner here in Orange County so I'm guessing I'll go 25-30k miles.
