From what I have read it does not work that well with the 6.4's. If you are going to do a delete, just get a tuner from one of the following:
Innovative, KEM, H&S or Spartan.
I have Innovative and it has been great for what I use the truck for, towing.
He can make some great power also with his tunes.
You will see the best mileage out of the higher HP tunes.

I wouldnt chance it, you get what you pay for. If you are going to spend the big bucks on a good truck go ahead and pay the extra $ and get a good tuner. H&S, SCT or Spartan you will not be dissapointed.

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.

The DPF-R simply turns off the Regen function much like the Tuners do at a fraction the cost. The only HP/TQ increase you get is that which comes from removing the big restrictor under the vehicle. It's Plug-n-play, no flashing of the PCM involved.

It actually works better on the Ford then it does the Dodge and Chevy trucks. On the others, you have to wait a few seconds before you start it so it can reset the regen counter but on the Ford it's completely disabled. No waiting involved just Regen Off.

I thought the wait thing was on the Fords only. Mainly from the way the regen is on a Ford.
Unless something has changed with them, I was thinking about them, but was swayed from them for the reasons above. I didnt want all out power, just get rid of the crap.

Smotrs is right, that is how the DPF-R works. I didn't use it much, after try the DPF-R+ (Eco-Tune); I have been using the plus. The DPF-R worked flawlessly, it does what is intended to do, but the removal and/or disabling of the emission control devices, add efficiency and also allow the unleash of additional HP and torque (yet been under the stablished operational parameters at GVWR). That is what the DPF-R+ (Eco-Tune) is intended to do.

I stand corrected. When I get time I will look for the threads on it. It has been a couple years though and searching for 3 letter words sucks.

If I'm understanding how the DPF-R works, it modifies the existing stock flash to disable the regens, or does it replace the stock flash with a modified version of potentially an older flash?

Example--with the Banks 6-Gun running inline with the ECM instead of reflashing it, I know for sure I'm running with my original stock flash that came with the truck.

The tuner guys must have taken a snapshot of a flash from a given truck at some point and then modified it. Do we know if they're using the latest 11B23 flash as a baseline?

Or does it matter if my '10 is running a modified '08 flash? (Nothing against you earlier model year guys!!)
