GDE Ram EcoDiesel Hot Tune

[BassDaggett]

Just wanted to give a shout out to Green Diesel Engineering. I had the Ram EcoDiesel Hot Tune put on my 2016 Outdoorsman Crew Cab 4x4 and so far its been awesome. Definitely quicker, significantly less turbo lag, more power when towing and better MPG (My commute is 79 miles one-way). I've hit 30+mpg several times in the past but it hasn't been a regular occurrence. Hit 30+ mph 3 of the first 4 days and saw 20+ mpg towing my bassboat. Well worth the money spent and at this rate will pay for itself in under a 100k miles!

My buddy loved it on his. He drives 30-36,000 miles per year, and he said it was worth every penny.

Yes, the GDE tune does all it's advertised to do. I increased my local mileage by 3 mpg. Most important is the EGR delete. I drive a lot of 8-12 mile local round trips and was regening very often. Now my regen happens at 600+ local miles.

Hey Diesel Guys, I've often wondered what rear end gears they put in the Eco.
Do you know what you have?

Not an Eco driver myself, but Ram offers 3.55 gearing as standard, and 3.92 as an option, with the EcoDiesels.

Pretty sure all eco D's are 3.92 from what remember.

Mine has 3.92, I do know you can get them with the 3.55 but it seems less common at least in my area

Nope, 3.92 is the optional gearing. It may hold true for for Crew Cab EcoD's with the 6.4' bed as I haven't heard of anyone chiming in saying they have 3.55 with that combination. Even some of the Crew Cab Outdoorsman with the 5.7' bed left the factory with 3.55, the 3.92 was a stated feature of the Outdoorsman package.

EcoDiesels where only built/offered with 3.55 or 3.92 gearing.
3.21 was not offered for any of the model years built.
