Different programs mean different things by the same JPEG quality numbers.

My out of camera JPEGS from my K5 are much larger than the JEPGs saved from my DNG raw files. Why is that? I save at the maximum setting.

Several possibilities:

  1. The "maximum setting" on your RAW converter is less maximum than you think.
  2. You've removed noise or otherwise smoothed the imgae in your RAW conversion, and there's less information to compress.
