6.7 Tuner

I'm going to be removing the DPF and probably the EGR from my 2014 F350. I don't want extra power or anything like that. It has plenty of power for me in its stock form. I'm interested in engine longevity and a decent fuel economy bump from removing the DPF. I also don't want to lose any of the engine/exhaust braking abilities when towing.


What's a good tuner that will accomplish those goals and not cost a fortune?

Since what you want to do is illegal, dont forget to factor in the cost of the fine for doing so.

Yes, thank you. I will certainly keep that in mind.

This might help though.

Just curious and not criticizing, but how will you get around the ecm’s objection to not having the dpf? Seems like you’ll need more than a performance reprogram and while Im admittedly out of my depth here, there are some non-reprogrammable parameters on these rigs and this may be one of them.

My son deleted his 2013 6.7. No more DEF, replaced the exhaust and its 10 sensors, and installed a tuner to avoid all the ECM error codes.

Send my a PM if you want me to put you in touch with him.

The tuners do exactly that. It replaces the software on the ecm so that it is no longer looking for the sensors associated with the DPF. Then you normally just unplug the sensors and put some tape over the ends so that they don't get clogged with dirt. With the 6.4 powerstroke I had before, I gained 15%-20% fuel economy. As long as you're not tuning for maximum horsepower, they aren't as pollutant as many people make them out to be. With a good tune, you can pass emission tests without the DPF and EGR.

Ive been tempted to do a 5 star or similar on mine but as you stated it has plenty of power stock. The only thing I dont like is the delay in acceleration from a stop or coasting, but I think thats programmed to reduce stress on the transmission and Im not sure if I want to change that.

I don't drive mine enough to be concerned about fuel economy and Im getting 17mpg during normal driving. Ive pushed it to 19 by focusing on economy (coasting a lot, rolling stops, lower speeds, etc) but 17 is good enough for me. What is your mpg goal? What are they capable of? I guess if I was towing regularly Id consider your strategy.

The goal is simply better fuel economy and better engine longevity. The emissions systems are what kills modern diesel engines. Remember the old Cummins and the famous 7.3? Those things lasted forever. Modern ones are better built, but choked to death by their emissions. They actually dump raw fuel into the exhaust stroke to heat up the exhaust to 1200 degrees and burn off soot. The solution to emissions is to intentionally burn more fuel? Really?

Agree Itchytoe, makes a lot of sense to dump raw fuel into the exhaust, raise the temperature to over 1000 degrees and burn more fuel and urea. All this plus the toll it all takes on your wallet and your engine life. The EPA needs to get out of the truck business. A well-tuned and fully deleted modern diesel burns clean and contributes less of an environmental footprint than farting cows and poorly maintained and out of tune gas junkers. I'll keep my fully deleted 6.7l and my 24.7mpg empty and 14.3mpg towing.

I'm about to do the full delete and have been running an SCT tuner. I currently get 12.7 towing and haven't check non towing mileage. 24+ I'll take that.

Delete, delete, delete all day long. Engine longevity is a definite benefit. Don't mind the forum police. We are all adults. Let us know how it goes. I have deleted three of our ranch trucks. It is one of the best things we did.
