Has anyone any knowledge on a aftermarket tuner to get the turbo to spin up a bit faster? I'm not happy with the lengthy lag when starting from a complete stop or anytime you may need an immediate "shot" to merge into traffic or get out of trouble. Looking....

My understanding is that what you are describing is not turbo lag; it is a delay built into the factory tune. Pretty much any of the aftermarket tunes available (GDE, Sofaking, MR Tuning, HD Diesel Supply, address that in their tunes.

I'm guessing since this is in the 3rd gen section that you are asking about a 2020 or newer EcoD. I don't believe anyone has a tune available for that yet though GDE is working on it and expecting a June 2021 release.

I had their tune on my 2016 and asked about the 2020, they didn't give me an ETA. June would be perfect as my new truck comes today and it will give some miles to decide that I need it. I mean, if....

Coming from a '15 which I was perfectly happy with until the AEM and never felt the need for a tune considering I was only planning to keep it through the 7 year warranty I bought. When I test drove the '20, unlike a few folks on here, I loved the performance and thought it felt like a gasser albeit not as quick as a hemi.
I'm almost 2k miles into it in a month and some of that has worn off because I'm getting used to t but I still see no need for a tune or Pedal Commander. Just like some people with the AEM, I think my truck runs and responds great....which was not the case with the AEM so I believe folks when they say it needs a tune, just not my truck.

I still see no need for a tune
I agree that the power is nice on the 2020, however, the purpose of a tune for many of us is to prolong the life of the engine. Just on the 2nd gen engine alone, the GDE tune gives a 75% soot reduction in the cylinder. Not only does that prolong the life of the engine, but it also extends miles between regens. Plus, the transmission is getting tuned and overall performance is improved (fuel economy, power, etc.). If anyone plans to keep their vehicle for the long haul, tuning makes sense.

oh, I agree with what you said but my comment was really in response to people complaining about lag in the '20 mostly.

Folks have to remember that there will be no legal tune that turns off the EGR and any tune could affect the warranty. My regen distance is over 400 miles so I'm happy with that.

That's true. But just to clarify, the GDE EPA compliant tune still gives a 75% soot reduction in the cylinder.

I don’t find the 2020 to have anymore lag then any other turbo diesel truck I’ve grown accustomed to and had in the past, even a f350 had a bit of lag. I just gun it

I am mystified by the fact that private companies can tune a truck’s computer to make it run more efficiently with less soot which in turn increases the longevity and still meet EPA emissions criteria. Why wouldn’t the RAM engineers do likewise? Certainly they know how to do this. My guess is they have been directed by upper management to produce a truck that makes through the warranty period (and is very conservative as to EPA emissions criteria)then after that who cares. That away they can sell more trucks.

Well, after all, they are in the business to sell more vehicles. Almost like making mobile phones without replaceable batteries or OS's that cant run on 2 year old hardware.

It's a valid question. Keith (owner and tuner of GDE) has worked for the OEMs in the field of diesel calibration, so he does have some inside experience. He would probably be able to tell you the ins and outs.

More than likely they design and build to an aggressive budget and the cost benefit just isn't there considering the vast numbers of their customers don't even know that the tune could be better...or even what a tune is if not a melody ;)

Understood and agree. I am surprised that they haven’t installed an algorithm that wipes all onboard computers at the end of warranty! Maybe once they have self driving vehicles at the end of warranty period the vehicle would drive itself back to the dealership for a new one!

I just installed GDE EPA-approved tune this morning on my 2015. Night and day difference. These trucks ran great until the AEM settlement. With that said, I just spent $1100 on the settlement FCA check and still came out ahead. Looking back I should have bought it sooner. As a person stated above, it was fine but I am really impressed.

Just look at the difference between stock and tuned, and the GDE tune still maintains the built-in safety parameters of the stock tune.

Well this is the first time I’ve seen this extensive list of benefits for the GDE EPA COMPLIANT tune and it still begs the question why the RAM engineers don’t adopt some of this aftermarket tuning methodology to improve their product so that the customer doesn’t have to pay even more cash for what looks like a better product. RAM CARES ARE YOU OUT THERE AND PAYING ATTENTION? As Fox Mulder and Dana Scully(X-FILES) would say “RAM DENIES KNOWLEDGE”!

I also added the optional "engine braking feature" and "regen message feature" when I ordered the GDE tune. It goes to show that there are lots of built-in options/features that Ram didn't allow the user to have.
