DP Tuner dissapointment

Have a 2014 6.7 that I bought a DP tuner strictly for fuel mileage. I bought this tuner based off of the recommendation of Powerstrokehelp.com's very own Bill, whom I trust very much. BTW, I opted for an emissions friendly 35hp tune for towing. Was I wrong to assume that I would actually see an increase in fuel mileage? What tuner should I have gotten for heavy towing and an uptick in fuel mileage or does that exist?

Without going to full deletes be happy with what you got. It may take more than 1 refuel to see any mpg increases.

I suspect the “room for improvement” is significantly smaller than the older motors. The 7.3 was so poorly tuned from the factory that the DP-Tuner turned it into a new truck. Still, call Jody and discuss your concerns. He’s a great person and will help figure this out.

I have done a lot of mods to my trucks over the last 18 years, some did help with power, but very little mpg gain if any. The number one mod for better mpg when empty is to drive slower. When I am pulling the 5th wheel not much seems to help.

I know everyone likes to jump all over ole Bill on powerstrokehelp.com, but I've gleaned some useful info from his videos. However, he did upset me when he announced he was done with the 7.3. Bill or not, I still love my 97 7.3 (which I am now selling because I bought a '16 6.7).
