Stock 2011, looking for improvement

[elanmechanic]

I have 50k on my 2011 350 dually. I'm looking for some better mpg without loosing torque. I tow 14k 5th wheel most of the time while on the road working. I'm needing some new tires also. Warranty is important because I'm not home enough to go to the same dealer when I have a problem or change out to the stock parts before going. I know the beast is in there just looking for the right avenue to let it out.

I am in the same boat as you, I don't want to lose my warrenty.

Without deleting, there is not a real good solution sorry.

With my '05 6.0 I put on an airbox and a tuner and it made a noticable difference. The good was I could pull the tuner off if I needed to visit a dealership. I would think there must be something of the same for these. I'm not looking for rip the tires of power, more mpg empty and towing without loosing torque. This is why I'm looking at going bigger on my tire size.

You will see a noticeable improvement with running the DPF ON tunes with H&S. The big improvement of the 6.7 over the 6.4 with respect to the DPF ON tunes is the fuel mileage isn't affected as much. The 6.7 is designed to do s lot of passive regens which helps significantly with fuel mileage. Buy a mini maxx and run it with with your DPF on and see how you like it. It would be the same as your 6.0. All you would have to do to take it in for service would be to put the computer back to stock and pull the tuner out of the truck.

This is probably the route I'll take plus going a size bigger on tires. I plan on putting on an airbox too.
