  • Fuel Economy improvements 3-5mpg.
  • DEF tank refill interval always aligned with the oil change interval.
  • Very broad torque/performance curve for better drivability.
  • Combustion changes to give best fuel efficiency and lowest soot.
  • For more contents of the GDE Tune visit the EcoDiesel Performance Data page

Please also be informed that:
  • New ECMs from Mopar are blank: there is no software flashed inside and these ECMs are not capable to run the engine/vehicle as-is. They must be configured first.
  • If mailing in an ECM for tuning that is blank or not the original from your vehicle, a $150 setup fee applies to have the necessary steps performed before tuning can be done
  • Blank ECMs or one not from your vehicle returned for the core deposit will be assessed the same $150 setup fee

Just back from a 3700 mile trip to Utah and Colorado. I was already loving the tune, but after being able to use the engine braking in the mountains while pulling my 3500 lb trailer, I love it even more. On several long steep downhills, I was able to just sit back and let the engine do it's thing. I am sure the brakes would have overheated. Love the extra power in the mountains and I know the mileage improved but is hard to track with such mixed driving. Definitely recommend the tune no matter what type of driving you do.

I don't usually write reviews, but I felt this product deserves one. For starters I was skeptical because this tune is really offering quite a package for a fair price. I'll start with the installation. I swapped out the ECM on my lunch break in dress clothes. All in all, it took me 20 minutes and was very simple. When I took my jeep for the first drive after the swap, the responsiveness of the throttle was noticeable right away. No more lag. No more feeling gutless from a stop. The change in power and torque has been a lot of fun. It's relatively simple the spin the wheels even at 20mph, which was impossible before. After finishing the first tank of diesel I noticed my range had improved greatly. The computer told me I was up about 4 miles per gallon, however when I check the math myself it is actually closer to 6.2 miles greater per gallon. On the first tank (while playing in sport mode A LOT) my average fuel economy was up to 28.9mpg. One change I was not aware of was the sound of the engine while ideling. My wife loves the sound of a diesel purr and when she heard the engine after I installed the tune she stopped and said it purred so much better now. I also added the engine break because I live in an area with a lot of hills. I love being able to set cruise control down a hil and have my jeep slow itself down without using the breaks. There are tons of other positives with this tune but I'm sure whoever is reading this is bored by now. Just do yourself a favor and buy the tune, you wil not regret it. One last thing, I took my jeep in for warranty work and replacmenect of all the sensors for the exhaust system as well as the DPF (this was an issue I encountered prior to the tune) and the dealership never noticed a thing, so don't worry. Just tell them you don't want them to update the ecm because you're happy with how it's running.

Don't know why I waited so long?? Just over 200 miles with the Hot Tune and mileage is up almost 5 mgp. I love the reduced lag on the turbo and I can already feel the increased pull on the hills I often travel. I decided to purchase it for pulling my Lance trailer. Just wanted a little more torque and can't wait to see how the engine breaking works. Could have used it several times on our trip to Alaska.

Great took 30 mins to install had to transfers a sticker so I won't get a reflash at dealer to be safe. This is well worth it no lag right off the line even cold. After regen mileage was impressive at 75 mph on freeway got all the way up to almost 30mpg. So smooth to accelerate. Almost no down shifting when you want to add throttle especially cold. Egr off going to make it so much more reliable. So my lazy trip home is going to blow my mind on mpg. Reliable, better throttle response and mpg to drool over with more hp. This is a must get for any eco diesel

Tune for Grand Cherokee is exactly as advertised. Noticeably more power, much better drivability, better fuel economy, all at once. Pretty amazing really. Before the tune my jeep would have to drop down to 7th to maintain speed on 2 hills that I routinely drive. After the tune I can now stay in 8th gear up these hills and even have enough power to accelerate. Big difference in power over the whole operating range. I have the turbo braking option and this works very well also. I use this daily. It applies very smoothly and is not obtrusive. Actually feels very similar to the engine brake on the Cummins 3500's. engine sounds a bit different after the tune. Not louder, but a bit deeper note.
