I havent heard anymore. Im waiting too but patience is running outAnymore recent news or rumors on the ED?. Still Patiently waiting, but very hard too at the same time!!
I can't speak for the ED powered Ram but my Grand Cherokee (being more aerodynamic) had a more linear decline in economy as speed increased. Diesels don't lose efficiency at the same rate under load as gas engines. Economy declines with increased engine load but not like gassers which take a noisedive under load or outside of their most efficient RPM range. That is why diesels have a larger payback when used for towing.Thank you for indulging me, ED. Now that I see the words, that makes perfect sense and makes me feel like "duh".
Can I ask you about highway fuel economy? We know the Hemi economy drops like a brick above 70 or 80 mph... but does the ED maintain good economy better at higher speeds?

Towing my 5k lb. cargo trailer with my diesel Jeep yielded 24 mpg. Towing it with my wife's v8 4.7 liter Jeep yielded 10mpg! My Hemi Ram gets 12 mpg pulling the same trailer. Unloaded my Jeep averaged 28+. My wife's Jeep averages 14. My hemi truck averages 16.4.
Driving fast is also a heavier load. Diesels are well suited for 90mph sustained driving since they are still reasonably efficient whereas a gasser is outside if its efficient range. I'd recommend the 3.21 if you spend a lot of time travelling above 65mph. My Jeep got 34 mpg at 65 and 30mpg at 80....a 12% difference. Mytruck now gets 20 mpg at 65 and 15 at 80...a 25% difference.
I always drove my diesel Jeep more agressively and overall mpg didn't suffer much. I drive the Hemi Ram more conservatively because mpg drops to 12-13 if I drive like I used to with the Jeep. So as an everyday driver, the diesel feels faster under normal circumstances even though it only had 246hp. It just had tons of torque that was delivered with little effort. The Jeep was full time 4WD with Skid Plates, Air Ride, etc. It weighed 5400 lbs. My Ram weighs 6090 lbs. and stays in 2WD most if the time.

I would suggest the GDE tune especially for a short commute. My tuned 3.92 gear Ram only gets 24 mpg ish at 80. Diesels do like being run warm for an assortment of reasons.
I was tuned with a piggyback tuner for a while but took it off. No other mods. The tune made a difference for sure. It was pretty agressive for a 5400 lb vehicle. 0-60 was 6.5 seconds and most of that was from being quick down low. I got concerned with warranty coverage and decided I'd rather be on the safe side since I have to trade every five years.Awesome. This changes everything and puts me back in the que for the ecoDiesel.
I don't live on the highway but I make a 2,500 mile trip at least once a year. At these distances, the difference between 65 and 80 mph can reduce the drive time by many hours. If I can do that and maintain "reasonable" economy and range-per-tank, it's a win-win. Call me odd but this excites me!
Are you tuned; GDE EGR delete, for example? Would you recommend getting that?
Yes sir, it does...but I can't drive like that all the time!Good points, @ExcursionDiesel. But the HEMI sure sings nicely at those higher RPMs.
