15psi @1400rpm sounds a bit high to me. we are talking about reving the truck, not driving it. if you are driving it, that could be ok.

mine mack had a corrosion issue, mentioned by mr challenger

deleting the trucks saved my ass, and since it was super hard to find someone to do it, that's why i decided to post it here on forum, to help others. my trucks are idling 80% of the time (running pto), and my dpf was clogging all the time. solution: http://truckecmtunes.com/

check out these guys to, they do it online through diagnostic port (no need to take off the ecm): http://truckecmtunes.com/

i got this done buy a company called truck ecm tunes. everything works like a charm. after putting the delete into the ecm, you have to block off egr and drill a 5" hole through center of dpf web site is: http://truckecmtunes.com/truck-dpf-egr-vgt-removal.html

i want to share my experience with dpf egr def problems. i own a fleet of 9 MP8 trucks, some of them are 2009, and some 2012. that means some of them are equipped with dpf egr, and some have def too. it's been a nightmare for me to run those trucks with constant failures of dpf egr def. so what i did, and what made my business running, is i went online and found a company called ecm tuneups. their web site is http://truckecmtunes.com/ . i contacted the guy, and he is providing his service through his authorized dealers only. that didn't work for me, since i didn't want anyone to know that my trucks are deleted. i asked him can i be set as a dealer, he said yes but i would have to wire money up front for every truck i did(according to what he said all new dealers have to work like that), and i would have to buy some equipment. i bought a laptop for $250, and a nexiq adapter for $300. he installed the software for diagnostic, and did a first tune for me. after that i put a 5" hole in center of the filter, and blocked off egr (both sides he insisted on that). result was OMG good. totally different truck. more power, no regens, no derates. everything worked well. i gained apx. .9 MPG. what i am saying is, that this saved my business. this guy is hard to reach, because as i said he works with his dealers only, but with some insisting he can make you a dealer. or if you have one truck, you can just tell him your location and he will forward you to existing dealer. if you have a fleet, it is a lot cheaper to become a dealer (i saved apx.$2000 a truck because i did all the work my self, and it only takes 2hrs to do the work). i hope this message will help other guys in need.
