14 echodiesel Bill L

[Bill L]

I have a 2014 1500 ram with the echo diesel, pushing 57000, love the truck rides better than my 94 Deville did, and got better mph till last oil change. I normally get 22 plus in town NS 28 TO 30 PLUS AT 67 TO 70 MPH. THE LAST WEEK OF Oct I GOT A FULL SERVICE and they told me they put a update into to my computer to help with better fuel economy, in stead it drives like it is in tow haul mode all the time and my mileage has dropped 9mpg had two other dealer look at it and they tried there best to get me to trade mine off for a new 2019 gas burner and told me the program was ok I must be buying cheap- bad fuel, I buy from my local Coop can't get any better than them any ideas ?

Welcome!

If the dealer says the programming is right, not much else to do but go down the road of a custom aftermarket tune.

So which one is the best for better fuel economy?
