The IMAP in particular has the pressure sensor up inside it and you can't get to it to clean it.The readings your looking at could be incorrect if the sensors arent reading right. Replace the doser also, it may not be spraying properly, that could cause it to not get up to temp during a regen. When you say the dpf and doc were cleaned "properly" what exactly does that mean? How did you clean them?

cleaned with this:

i was leaning toward the turbo because it seemed to get worse as it warmed up but i didnt feel all warm and fuzzy about replacing it. its expensive and i didnt want to blow somebody elses money on it if it didnt need it. my plans were to replace those sensors and doser tomorrow and clean the egr valve and piping. then see what kind of regen it does after that. i think i will remove the turbo actuator and check the turbo linkage as well for binding. i just figured it would be worth a shot to post it on here a get a different opinion. thanks for the reply.
