MystRacing, Just realized you were posing a question to me (us). I really can't tell you if the cleaning is really good for V6 or I4. But I can tell you my experience. I had the EGR passages cleaned at 60K and 80K (eventhough I didn't have the 401 or 402 codes). My DPFE still works fine (no codes or idling issues attributed to it) at 83K and 9.5 years. So take the advice for what it is worth. Good luck.
