This doesn't sound like an EC issue, but an MB tranny issue. I ran EC tunes forever and never had a problem. Also -- 2013. Perhaps the year and OEM software updates have something to do with this?
The fact you went back to your stock file and still had to problem has me pointing all fingers in MB's direction.

Be very careful about reflashing after the dealer has updated your software. Talk to EC, ask lots of questions, explain your situation clearly, and get their assurance that what you are doing is OK.
This comes from painful personal experience. I reflashed my EC-tuned car back to stock because the tune was blocking an emissions test. While it was on stock tune, the dealer updated the ECU during a routine maintenance visit. I had no clue that this could cause problems. EC evidently did know but never asked the right question. Total communications failure. When EC flashed the tune back in, the reflash bricked the ECU. Nothing EC or the dealerships did could salvage the ECU. I was out of a car for a month and dropped almost a grand getting it fixed. This was avoidable if the right questions had been asked. I hope my bad experience can save others from similar pain.

The right question to ask before flashing the tune back in was probably "has anyone flashed this car's ECU program after it had been returned to stock?"
EC never really explained what happened - perhaps they would be willing to jump in and explain this more clearly so nobody else gets bit.

Quick update since I've gotten a few pm's asking.
Car went in to the dealer yesterday morning and took a drive with the tech first thing. Obviously I had no problem reproducing the problem and the tech confirmed it had a flare in the upshift.
I got the update today that he did a relearn of the shiftpoints (whatever u call it), he did a test drive yesterday and again today. He tells me the flare is gone but the car will be there until atleast tomorrow tackling a rattle in the door that came down to the window switch and needed to order a new one.
I'm still skeptical until I can drive it but hopefully I'll have it back tomorrow.
In the meantime, they gave me a '17 e300. Love the tech in this car but man, it has no ***** lol

As I thought, I was skepitcal about the dealer saying the problem was resolved since there is a specific amount of throttle needed to produce the problem. I just dont think the tech has enough seat time in my car to be able to reproduce the problem at will.
The tech told me that he did adaptation relearn but the computer would only allow him to do it in C mode. When he tried to do the relearn in S and S+, the computer would not allow it. I havent been able to reproduce the problem in C mode but it still happens in S and S+. Strange huh..
So the car will be headed back to the dealer to dig deeper.
On a better note, the tech fixed a rattle in the rear deck by applying felt tape to the 3rd brake light and few other areas. Also fixed a door rattle that traveled through the dash and came out the side vent. The driver side window switch had an internal rattle so the switch was replaced. Car is currently rattle free but im sure something else will pop up lol. There was also a tear in the felt trim in the pano roof (no idea how that happened) but they labeled it as "discolored" and the whole panel was replaced under warranty.

I had the v5 on my ml63, and I had a part throttle bucking surging, that drove me nuts. Would go away if I reset adaptations. But who the hell wants to have to do that every so often in a 100k car? Not a fan of am tunes on a dd merc.
Gl. I would just put the stock tune back on a 507 Ed. Not worth the hassle, and non merc driving characteristics IMHO. Gl
.....no flames please... Just my 2 cents from my experience and after spending my hard earned $$$....

Until the dealer can figure out whats going on, it appears to be an issue with the trans BUT the v6 tune made it much worse and more frequent

I am not downplaying the quality of the Eurocharged tune. I want to make sure everyone knows. I am saying please make sure you know your cars problems with shifting and have them addressed to the best of the dealerships capabilities before considering a tune. I have noticed my issues of shifting has come to the gas quality I used. I am on the considering factor of purchasing a tune today. Before pulling the trigger does anyone have any negative review before doing it?

It seems EC pays MBWORLD the most money and has the most "social" face so any issues or problems that arise are quickly blamed on the users themselves and not on EC and EC manages to disappear/vanish.
I recall some "seasoned" members defending EC stance on charging upgrade fee even when they claimed there was never going to be a fee and than those same members criticized others for being cheap for driving a C63 and complaining about $35. If you step outside MBWORLD you will see there are many other options than EC and the EC bandwagon *** licking is a real deal over here.
My 2 cents. Either way it made me realize NOT to go to EC. OP keep us updated what dealer in long island are using?

Update to my issue.
Mods when I had part throttle hesitation/chugging:
Eurocharged v6 tune, ARH catless headers and x-pipe, charcoal filter delete, Weistec dry filters.
I started to have MAF sensor stored codes (still US airboxes). I think the increased airflow of the headers and the lack of charcoal filters was causing the MAFs to trip out. I swapped to ROW airboxes and all the stuttering and hesitation is gone. Throttle inputs now result in smooth acceleration. I didn't try the stock airboxes with charcoal filters and stock filters, but maybe the charcoal filters and stock filters have a straightening effect for the airflow going into the US airboxes.
Bottom line: the tune was fine. the other mods were (or lack thereof) not playing nicely.

the reason i asked OP to look into his filters were to rule out the possibility that it could be linked to that. i had similar hesitation issues. i was battling it for a while fully believing that it was an issue with my EC tune. but it wasn't. i had some codes checked including stored codes. replaced 2 o2 sensors, fixed some exhaust leaks, changed my dirty filter and replaced with k&n, and fixed and replaced all the airbox screws with the new updated ones because the previous ones were rusted and broken possibly causing the lid to not be tight. i jumped from v4, v5, v6, in various stages and of course the stock tune and i was still having the issues until i did everything listed above. and then my hesitation and weird shifting issue went completely away. i tested on the stock tune, v5 tune and the car would drive beautifully... i then went to v6 and it was smoother than ever. felt like driving a brand new car. i seriously had no doubt that it was the tune's fault that caused the issue but in the end i was dead wrong. it had absolutely nothing to do with the tune that jerry provided. i just needed to take better care of my car i guess. now i'm enjoying driving my car more than ever and i'm almost at 100k miles.

I think I'm going to order the row intakes with BMC filters and run them without a tune for a bit. See how I like it first. I wonder how many people run this setup without a tune?

I can tell y'all from my experience (if you don't know feel free to ask) A TON of problems are due to user error. If anyone is using "DIY ROW Airboxes"... you will have issues. I have removed and thrown in the garbage many sets over the last 10 or so years because someone thought they were being clever and took out their charcoal filter, or worse yet, took a dremel to the velocity stack
The M156 is extremely sensitive to airflow charges over the MAFs. As a fun experiment you can do yourself at home: (if you have ROW boxes and drop ins)
1. go warm up your car and pop the hood
2. with the engine idling, pretend like you're 14 years old and trying to blow out all the birthday candles...
3. use your super blow and direct it into one of your snorkels
4. you will most likely (if you are enough of a blow-hard) notice a mild-moderate fluctuation in the rpm.
end experiment
It can be noticeable sitting in drive at a stop light, and a gust of wind comes up, the engine may feel like it gets a sudden surge, or anything like that.
Point of my story is don't cut your boxes... if you want ROW, buy ROW - don't be a hack. otherwise, the MAF's are sensitive.

Thanks, Dave! I didn't dremel the boxes at all. I'm not THAT dumb. Haha. But yes, I noticed that at least my car seemed sensitive to MAF changes. It even stalled on the first start with the ROW boxes until the adaptations were reset. That v6 tune...it's smoooooth.
