    Here's my experience with the GDE tune:

    Once the active regen message shows in my EVIC display (the message says the filter is 80% full) and if I'm not traveling at freeway speeds I try to keep the engine between 1,500 & 2,000 rpm by manually shifting gears. Once the regen message shows that the filter is 70% full I know that the active regen has begun. I've found that at this point I can drive at whatever speed I want and the regen will finish. I can also park it at this point, the truck will cool itself while parked, and the regen will start again when the filter is again 80% full.

    (This morning I completed my regen at idle)

If I had known that this truck cannot operate strictly as a city truck, I would never have bought it.

    The biggest annoyance is that I will start the truck, with no prior warnings the info screen will say "filter 70% full, drive at highway speed to remedy" and then within a minute or two it's at 90%, and I'm forced to drive 8 miles out and back into town for it to regenerate. Not exactly convenient. The dealer says this is normal with the ecodiesels. It's the only thing that I dislike about the truck. The time it went limp I had less than 2 miles from initial warning to limp mode.
    My 2016 has 33,000 Kilometres in the last 12 weeks mostly in the city I have never seen a re-gen message at all and I don't really care what's happening under the hood as I just drive it I have no tuner I have no problems

    And if I do have a regen going on I sure as hell wouldn't go out of my way to finish it it will finish it when I get back in the truck

    I have considered trading for a hemi but instead of loosing money going that way I am now also thinking about the GDE tune. I too like the truck in every way except for the frustrating, annoying frequency of the regenerations. I too wouldn't have bought the ED if I had known they would occur this frequently.
    I ended up getting the GDE tune about a month ago and have yet to see a regen since.

    I'm located in Wyoming at about 5,400' elevation. Most of my driving is either short trips in town of a mile to two, or trips up the canyon to ride mtn bikes that are about 10 miles each way.

    I was not worried about some catestrophic failure, but the truck did go into limp mode and sort of strand me when the filter hit 100% full and it would not regenerate. That's what I am worried about because only the dealer can do the forced regeneration (or at least I can't).

    Hopefully the GDE tune sorted it out, it's been running well since and improved MPG.

    It is very possible that you have only seen one regeneration, but the reality is that you have likely had over a hundred regenerations.

    I'm going to guess you had at least 50 regens in 10K miles if you have the stock tune. If you have the GDE tune, you probably had a dozen or so regens.

    I am looking into the GDE, so my question is how does the GDE tune limit regens? Does it truly make the motor burn that much cleaner or sometime down the road are we going to be in trouble because the GDE tune did not allow the truck to clean its emissions equipment. That is my concern; I'm confident that the answer is going to be, yes it is that much cleaner, but I would like to know how in some detail so I can put my mind at ease. I would really like to purchase it, but like many, I bought the diesel to last and I don't want to put the GDE in it if it is actually going to make the longevity less.

    Thanks all

    Yes the GDE produces much less soot than stock. It also changes the initial regen trigger from 65% to 80%.
