I noticed that there are a couple of newer TSB's that I just resently found out about. The first one is 14-004-11 Apr 11 Fuel sys HD Mopar Filtration Kit retrofit. Second one is K01 May 10 ECM update for OBD readiness. I called the dealer about them they told me that if I wasn't have an error code I did need to do anything about them. That somehow doesn't make sense to me. What say you good people of TDR?
