My truck is a 2008 w/ EGR blocked and DPF delete between other minor enhancements. I have been using the DPF-R+ since 5 month ago and I am very pleased with it. It seems that gives the maximum reliably attainable by the 6.4 without the emission control components. It gives more power and a lot better low RPMs response. With it, the maximum temperature reached has been 1420°F and 43PSI of boost pressure, and both maximums were not reached in the same event. The aforementioned values are just bellow the maximum operational established by Ford which are (in my best remember) NMT 1450°F (EGT), and 44PSI (Boost Press.). No codes, not even one problem with it. About the fuel consumption (unloaded), if I am mostly in highway it gives around 18MPG (@ 65MPH or less, w/3.73 gear ratio), combined 14MPG, and the worst in city and idling around 11MPG. In my case there is a 6MPG difference between the computer reading and the hand calculated one. As an example; if the dash reads 22MPG, I usually obtain 16MPG hand calculated.
Since I was looking for reliability and longevity, I am very satisfied with the DPF-R+. If you are one of those that don’t want to be back and forward trying different programs in your truck (as for daily driving or towing, because drag racing is another world) and been subject to constant transmission learning periods; the DPF-R+ is a good option. I have been constantly monitoring the operational conditions of my truck and deem that a close monitoring is unnecessary since the EGTs and Boost Pressures have been always (without even one exception) under the maximums recommended.
Being within safe motor operational conditions can be extrapolated to be also good for the transmission. In the other hand, higher EGTs and Boost (if well tuned) means much more power, but if the transmission and/or other components remain as per the original design, you will have many weak links. All is about how you manage the risk, many are clear of it, many are not.
