I have a 2014 as well, and am very impressed with the stock mileage. 3.42 ratio helps when unloaded, but I do have to limit my trans to 5th when pulling, otherwise it shifts a bit crazy. Engine spins a low 1500RPM at 75ish MPH.

These truck also have the axle hub disconnect system in them, and I have heard that will have gains up to 1 MPG.

My computer has shown 24 MPG empty down the hiway, and about 13 MPG with a 8,000lb holiday trailer in tow, and a quad in the box. If I didn't have a heavy foot to get to my favorite spot, and all the slow hills and turns to get there, the 13MPG would go up significantly.

Damn. maybe I should upgrade.......:humm:

Don't if your looking to Mod your truck, at least not the 13/14 trucks. Can't delete emissions, 3 electronic power adders, intake, and emissions back exhaust is all you can do at this time.

Thats good to know. Ive been bouncing around the idea of selling my supercharged chevy dually, and getting another dodge ctd. Maybe in the 10-12 range. THat chevy of mine is a thirsty son-of-a-buck!:nope:

I've had my 2014 Ram CTD for 2 months. On a trip last weekend I averaged 20.4 mpg (hand calculated). The inboard computer was saying 24 mpg. The best I've done towing is 11.5 mpg. Towing appx. 9600 lb travel trailer.

Yeah, ya cant really rely on that overhead gizmo. My absolute best mileage, doing 65 mph, was a GPS corrected 22.5 mpg. I think thats fantastic for a dually with a snug-top shell, and running empty. That was on a 1100 mile round trip. The overhead was indicating a steady 25.2 mpg. Way optimistic! Sure would be nice though.........

My Dodge ram 2500 6.7 full stock.. I drove on the highway 95% almost 20 miles..

I think best drive 65mph about 1500 to 1600 rpm.. get 18-19 mpg. City 13 to 14 mpg I do hand calculated.

Gas station walmart diesel

planning to delete kit soon :)

THats not too bad for that big 6.7 bro.

I have my mega cab dually 4x4 with full bumper brushguard and full wrap around bumper. I have a toolbox headrack and 100g tank filled. fully deleted dpf and egr. I average about 17 taking her on a trip probably about 500miles to san antonio tx. I ll let you know my mileage. Went to get my truck weight and she weighted out at over 15kunloaded? is that right? sounds a bit heavy....

That weight reminds me of my former mother-in-law. Diet time!:w2:
