2001 7.3 poor mpg, lack of power

Any other ideas on this? Here are some datastream items from my scan tool tonight...this is at op. Temp at idle.
Icp 475 psi
Vol fuel desired 10 mm3
Manifold guage psi 0
MAP 12.2 psi
Ex. Back pressure 18.97
Ipr dc 11%
Ebp reg dc 0%
My questions, are the map sensors on superduties off compared to a mechanical guage? While driving my boost guage to manifold psi on scanner varied by 2-5 psi. Ebp seems high by about 5 psi...should be around 14 psi at idle? Anyone know the boost to backpressure ratio of the stock garret 7.3turbo? CSIPSD, what do you think?

stupid question but sometimes the smallest stuff makes a huge difference have you checked your fuel filter? ive herd them getting clogged and killing mpg just a thought ?

CSIPSD knows his stuff, might want to powerstroke.org there's alot of mechanics on there they might be able to help

Yea, I have probably changed it 2-3 times since this started. Unfortunately with my luck lately its not something that simple I really wish it was though!

Ya he is pretty knowledgeable with powerstrokes. He Has not replied to my post lately....maybe he is stumped as I am I may post over there someday...

diesel kleen sucks, it doesnt do a whole lot. im not much a fan of any of the additives except for schaffers, its the ONLY additive i have ever seen do anything for me. it quiets the injectors and ive seen a slight milage increase. if it is getting good airflow in and good airflow out without any excessive smoke it very well could be just fuel ive noticed fuel getting worse and worse, do you fill up the same place every time? do you rotate where you get fuel from?
