So I'm in the same boat. No symptoms whatsoever but have P0172, P0175 and P0420, P0430. Cleaned the MAF, checked for vacuum leaks, and just changed the file filter and regulator. I haven't done the recall on the software yet but will lose the Dinan Tune that was in the car if I do. Any other suggestions out there?
