I had the update done and I had a serious lag 2 days later. My first thought was o no whats going to happen in winter. Much to my surprise the lag only seems to appear during warm up. I did drop 2 to 3 mpg average after the update, I added some FPPF to my last fill up as cold is in the forecast and gained 4 to 5 mpg average since. Average mpg has been 22 in this area until the update then it dropped to 19 until I added the FPPF now I am getting 24.

So I had the AEM flash done today. I was talking to the service advisor about the impending EGR recall. It appears my truck is part of it. Apparently there will be a new EGR and cooler. Right now there are no parts available.
I haven’t driven much yet but my performance appears unchanged.
The only thing was my oil life indicator went to 0 and big red letters “change”. However when I cycle through the oil menu it still says how many miles (6490 in my case) since the last change.
I will be installing my GDE tune this weekend along with a fresh oil change. After the EGR replacement I will install the SFT transmission tune I recently purchased. Also going to try to get my intake cleaned at the time of recall.

Got my '15 gc back today after the aem update. Only driven about 100 miles so far, but fuel mileage seems to be the same (averaged 27mpg over that 93 miles with mix highway/city). However, the cold engine lag was real. When i first picked it up this morning, I tested it at the stop light. What used to be an approximate 1s turbo lag with cold engine is now about 3 seconds. Once the engine is warm, I never noticed any lag before. Now I have about a 1s lag. I find that if you try and just mash the accelerator it makes it worse. If i slow and steady the peddle, I don't notice it, but acceleration overall is then slower. I didn't notice any change with the transmission or shift points even when going up inclines, including steep ones. Easily did 70-75mph up a steep incline (santa susana pass in CA) and stayed in 8th gear the whole time. As it is my work vehicle, I carry about 500 pounds of equipment in the back at all times.

Will see how it does over the next few weeks fuel wise, or if any lag changes and report back.

Also, I spoke with someone (sales department) over at Banks today and asked them about the derringer tuner and he flatout said it would not change the turbo lag issues unfortunately. So I may have to see if SFT is still available in california. Just curious if anyone who has been using it for a while has run into any issues with flash counts and warranty issues?

I think eveyone should demand the intake be cleaned while they are in there. when did you buy the GDE tune? i need it but they stopped selling it for now to US customers.

Heard back from the law firm , they asked my permission to send my information to the DOJ and my VIN number. I also got my settlement check today, now I have to figure out what to do. Will wait a while and see if a fix comes, in the meantime I guess pay off the truck.

I purchased mine in late Sept. I think. It has been sitting in the garage waiting for the AEM. I changed oil today and installed it. The installation was easy and took less time than the oil change! Followed the directions and had to drive for about 30 miles or so for the REGEN message to go away. The truck seems to run great. Now to get the SFK transmission tune in! Will probably use the settlement money for new tires and a leveling kit.

Bought my Eco used less then a month ago and found the recall notice. I called my local dealer and asked about it. He told me NOT to do it at this time because of all the performance issues and to contact him in 6 months to see if they’ve addressed the problem.

Hi Guys,

Same thing here! Loaded 2016 Grand Cherokee Summit with 27,000 miles. Had the update done in May, and just got the Check after many, many delays on 11/10. The Turbo Lag is unbearable and dangerous. I tried to sell Car to friend who really wanted it as it is a cream puff but can not get over the poor drive ability.. With all the EPA threats on Diesel Tuning, I am unsure who will tune it. Been to the local Jeep and they look puzzled about the lag. I know Jeep is coming back with the Diesel and had to improve the tune or no Diesel Jeep would ever be sold again. I am unsure what to do but have to do something!! Suggestions Welcome. Thanks Dan Dement 210 262 6608 cell

Well. Unfortunately only a few options at this point.
1. Do nothing and wait and hope FCA comes out with a better update to correct acceleration lag (not technically turbo lag as the software delays engagement of the turbo intentionally). Deal/anticipate cold-engine acceleration issue, but take comfort you are covered by warranty should anything go wrong, including possible engine fires that have cropped up following AEM update. (i feel there has got to be an update/fix in the works, problem is how long will it be until it's available).
2. Tune it, improve all aspects of performance, longevity of engine and drive til it falls apart. Don't expect any warranty coverage and be prepared to pay for any needed parts/repairs out of pocket. Reflash as needed when going in for service/warranty work and hope you have a really nice dealership you use that might be tune friendly and not watch flash count too much. Take the warranty work they do until they just say no.
3. Sell it, take the monetary hit, move on to something more enjoyable.

Thank you for the reply. I have a call into the Service Manager and going to start a “build some repore” relationship with him. I have bought over 20 vehicles from the family owned dealerships. I think it is time to complain to Jeep Factory Rep and talk nice and try to get more than going into A.H. Mode. It is “Tune Time” In Texas! I should have never done the $3,000 rebate and just sued them! I will keep the Forum informed. Thanks for the help!

From everything I've read and peoples reviews it sounds like it does. I'm still not sure what the rational is for creating such a long delay before engaging the turbo. If fca would just remove that, or shorten it significantly, they would make 90% of the people happy.

If I were to hazard a guess it's probably because some of the worst emissions are during acceleration especially when the engine is cold and it is an area they had to address to be in compliance. I suspect it is more than just delaying turbo engagement. I bet they are also limiting the amount of fuel that can go the injectors during acceleration until the engine reaches a certain temp. Regardless of whether it is either or both - the solution provided in the AEM update is horrible from a drivability standpoint...

Guess I'm a little surprised that Sofa King is still selling offering an ECM tune after the latest regulations on aftermarket products went into effect. I tried to purchase a GDE tune last month and was informed they couldn't sell one to me anymore. Let us know how the tune works for you.
