haven't got one Booked in yet due to Xmas holidays.
Yes its supposed to be smoother. With the smallish turbos on the M276 massive top end gains aren't possible. But then that's why the low -mid range torque is so good and comes in so quick. Especially when tuned, it actually behaves more like a big displacement NA engine.
But why does the facelift make less power at the top than the pre-facelift? I checked with the OP - he does not have OPF, so that's not it. I hope they crack it soon.

yes non EU cars wouldn't have an OPF.
The facelift has larger turbines from the E43 to make up for the increased back pressure on EU OPF cars, so overall same torque and small increase in power compared to pre FL.
Why do non EU cars have the problem of making less gains on remap? Tuners are not using facelift specific tunes on the facelift cars, that is the only reason I can think of.
When I was at MSL who use Eurocharged maps, when selecting my car model, only the option for the 362 BHP 2017 Model was visible not the facelift, on the ECU reader.
I think Renntech , GAD, and some others do offer tunes specific for the facelift but they're not available here or a lot more expensive.
if I was in North America I'd still go for Eurocharged. EC Canada have the fastest stock turbo C43s in the world.
Failing that I'd go to Renntech.
As I Said before, regardless of dyno figures my car is a full second faster to 60 mph and in the 1/4 mile.
Remember it's the area under the curve that matters more than the peak gains. The top end power stays strong till 6K rpm and the torque curve gain is huge. Let see what the new dyno says.
I wonder why none of the tuners are willing to develop a tune specific to 2019? If it’s not due to the exhaust, and the engine is the same, but the turbos are different, what’s stopping them. Perhaps the 2019 turbos just aren’t up to it?
For the sake of discussion, if I put 2018 turbos in my 2019, could I get 2018 power on the EC V4 tune?
Maybe 2019 cars just need the older turbos to unlock the power.

It would not . As I said earlier the turbines on the facelift are larger than the pre FL. It's a software issue, if EU then also due to OPFs.
So what you’re saying is that it is a purely software issue (outside EU) that the 2019 isn’t able to make as much power as the earlier models.
it seems so. The correct software makes a huge difference.
Either way, if you have a 2019 and remap it, it will be bloody fast- 3.5 0-60 mph and 11.81 1/4 mile are insanely fast.
A standard C63 would not stand a chance, and a tuned one would need perfect dry conditions to beat it below 100 mph.

wow. Hope I can join the party one day. I would be happy with 12.0 flat and no cel. I will tell you the best gauge in my car pinned so fast and the renntech tune was awesome. Just done get why running so rich. Still waiting for response. Maybe they just need to lean the fuel curve. The leaner you run the faster , but to lean is when you blow your engine.
Do we know any key differences in the 2 cars. Original to facelift. I understand foreign markets have this extra filter in the exhaust. I’m in USA. I heard the turbos were slightly bigger on the facelift. I also heard they put out 2lbs less then the original. Put my car back to stock. Drove over 50 miles. No cel and idle was back to normal. i got light for 2 o2 sensors running rich. That’s definitely the tune. Not my car. Is as easy as just leaning down the fuel tables. Lean turbo cars always made more power. But to lean and you can really hurt the motor. Any thoughts......

Your exhaust is the same as the pre-facelift exhaust. Your engine is the same as well. Turbos have different part numbers. We can only guess what’s the real reason the facelift gets less top end power than the previous models on the EC tune.
AhEmGee says it’s software, that implies the programming in the ECU is slightly different.
We have to wait until EC makes a breakthrough with the 2019.
There is no restriction in the exhaust, not possible, as far as I know.

Thank you. Just don’t get why they told me numerous times, it’s the same tune. No increase in power over previous year. I’m not gonna be out 2g for a tune that does not work. I’m anxious to see what there plan is. But other people on here have had 19 cars with their tune and no issue. I went with them for ease of install and reliability. Eurocharged I need a windows laptop which I’d don’t have and more pain in my *** to install program. I will put not tune it if they can’t fix it. Very disappointed. I did file a procedure with my credit card company for refund if they can’t fix.
So took my car back to EC Canada today. They took a look and recommended catless downpipes. i don’t want to go that route. So as of now my car makes 385whp and 482 torque. For some reason 2019 def make less than pre facelift. Hoping EC can figure it out soon so I can go get re flashed.
here is a pic of my dyno. Notice the top end power drop. they said it may be the TCU limiting it. Who knows.

Did they say how they will approach the problem? Or give a time line on the solution?
Otherwise, I fear they’ll just flash another 2019 and tell the customer the same thing and then another and then another. Won’t they need an actual car to solve the issue?
I sent my renntech back. I was not comfortable with them updating the tune without seeing the car. I’m thinking of now getting a piggyback. Not JB4. Either the new VR Tuned with only uses 2 sensors nor the Racechip S or R version. Not looking for crazy power. Now my ECU was flashed twice. Once for the tune and then back to stock. I hope I dont have any issues. That’s why in looking at a simplest piggy back on the market. Any thoughts ....

A used JB1 if you can find one? That’s quite a simple box.
I’ll be selling my Performmaster tuning box once Eurocharged makes a breakthrough with the 2019.
Maybe. The new vr tuned version 2 for the facelift only uses 2 plugs. Boost and map. Adjustable. Set for 91 octane or you can increase to 93 octane. I’m not sure how many sensors the racechip uses. I emailed them today. What is your perfomaster ?
Ok. I’m kinda liking the new vr tuned. Only 2 wires. Not looking for crazy any more. Still disappointed in renntech. It’s flat out obvious the 19’s are different then previous models. Even the piggybacks are making different versions now.
Did you have one of their latest Renntech ECU+ HHT (either $2,240 or $1,980 MSRP)? Renntech says software is not returnable. Is that the one you have returned? If yes, did you buy it directly from Renntech, or Mercedes Benz Authorized Renntech dealer, or a "third party" (non Mercedes) Renntech Authorized dealer?
