I wasn't a believer of a tune until I knew more info.
Not only will you get the optimum output from the engine(m156 was built to go over 500+hp) but a tune like Eurocharged will keep all factory safety restrictions in place. It also makes shifting smoother which was the main reason I wanted to tune the car. It shouldve came from the factory like that. The eurocharged tune also eliminates the lag. Definitely the best investment you can get for your car.

With MB being such a big company why didn't they come out of the factory like that?
Thanks so much for the info, I really like the idea of keeping the safety restrictions on to protect the engine

I also think it is worth it, it isn't so much about the raw increase in power, but the drive-ability and just improvements in smoothness and shifting (even though they don't retune the transmission, the ECU values significantly affect the way the transmission reacts for the better)!
It's worth it. Remember that our little C63s are the smallest and cheapest car with the legendary M156 motor. There are different factory "power levels" from this same engine, and it's entirely a marketing/sales tactic to establish a hierarchy, power-wise.
I'm looking at getting a tune for my C63 p31 but was wondering if it is worth it since it already has a revised ECU.
I'm in Atlanta if anyone had a suggestions for a shop that offers a dyno tune.
We just had a dyno test/tune day about 3wks ago at the shop in Acworth....Tony is the only person I let tune my cars anymore....if he doesnt respond to pm then pm me your number and I'll have him give you a call
I bought my C 63 P31 with a tune already installed, but I recently upgraded to the euro charged V7 and I love the power and drivability.
No bull****, on the highway, I get 21.5 or better mpg at 75 to 80 mph.
so, while I can't comment on whether it is worth the investment to go from factory P31 to a eurocharge tune, I am happy with my eurocharged V7.
The previous owner of the car bought the upgrade for me, but I will likely be paying the $500 transfer fee in order to get updated tunes as I modify the car.

P31 is already 500hp+ (it´s 507, just like the 507 edition, and not the claimed 487)

you're going to want to take anther look at whatever article you are reading lol. But what i meant by that is the m156 engine itself is built to exceed 500+ horsepower. There still will be a gain even if he has the P31, just not as much as non P31

Sure there is a good gain, but not from remap alone.
What I mean is the test many have already made:
P31 and 507 inthe same day, same Dyno and same track. They both have the same hp and accelerate exactly the same. Pepple have alteady contacted AMG engineers and it was confirmed it’s the SAME tunning and the special edition with the nice bonnet is just to cash a bit more.
I’ll paste here a famous text from THIS forum,, and it’s just one of them:
From what I was told by someone "in the know" at one of the MB corporate stores in Toronto, the 507 is essentially a 2012/13 Canadian APX car (P31+P30+LSD) with the BS hood, new wheels and different door trim (he had just returned from a training trip at the MB head office in Germany). I was inquiring about the possibility of putting on the 507 ECU tune on my car in order not to void the factory warranty, and he said that even the ECU maps are likely not going to be any different.
While the regular C63 is intentionally de-tuned, the P31 & APX engine horsepower figures are underrated for marketing purposes. Every P31 or APX car actually delivers more than the rated 481 hp (487 in Europe), usually upwards of 500 as numerous dyno tests have shown. The numbers are intentionally misrepresented in order to justify the price premium for the Black Series (delivering the same power), other more expensive cars using the M156 engine at the time (-2008 S63, E63, SL63, CLS63 & CL63) and, more importantly, the SLS AMG which is 2.5 times the price of the P31/APX. While the SLS does have a somewhat reworked motor (M159) with a dry sump and other modified bits that the P31/APX M156 engine does not, the difference needs to exist at least on paper so that the sales of the other more expensive AMG models do not suffer as a result. The 507 will be the last iteration of the M156 engine before the new 2015 force-fed C63, and it's just a face-lift so that MB will still manage to sell some 2014MY C63 cars.
While the gent I spoke to at the dealership knew that I had just bought a loaded 2013 car and it is conceivable that he was just saying this to make me feel good about my purchase, I have no reason to doubt his story as he is very high on the technical side of the corporate ladder if you will. I was told this is the reason why the 507 won't be brought to Canada as it is exactly the same car as a loaded APX vehicle except for the hood, wheels and exterior door trim. In other words, they are not really changing the car - only the *claimed* power rating. If he is right, then the 507 should produce exactly the same power as the current APX, P31 or tuned C63 cars.
Ok so hearsay evidence from the usual source - an anonymous person with insider information.
Are there independent dyno results confirming that the Canadian C63 makes as much as the 507?
I tend to agree. I've read a lot of the same posts. No one seems to actually know whether that is true - just a lot of e-peen statements. I don't put a lot of stock in the "I know a guy" statements. Show me the back to back dynos. Not a dyno of a PP car in some other part of the country on a different day compared to a 507. Or better yet, have a reputable tuner say whether the stock files are identical with the PP/APX and the 507 cars. Correct me if I'm wrong, but that seems like it should be a fairly easy thing to do. When I load maps with my AEM EMS4 or a EFI 1.2 or anything else, it is awfully easy to see changes from one map to another...
Back on topic, I have a 507 car and have not pulled the trigger to tune it yet. I intend to do headers and a supercharger, but will wait until my warranty runs out. Given the relatively small gain from a tune alone on a stock 507 car, I can't justify the warranty issues regardless of drivability improvement, etc.

I just raced a 2013 c63 coupe with a v7 eurocharged time last weekend at the 1/4 mile track. At first we were pulling 12.8 at 113mph. After about 8 runs, he had his down to a 12.2 at 116. I was stuck at 113mph. He kept getting faster as he did more runs. His was a non-p31.
I was told this is the reason why the 507 won't be brought to Canada as it is exactly the same car as a loaded APX vehicle except for the hood, wheels and exterior door trim.
Except it's not, because in the USA the 507 did not come with the LSD standard. $2K option.
It's worth it. I gained 40whp and 50wtq on a P31 car.
What was your baseline #'s?
Do you feel like the power is there all the time, or do you have to beat up on it for a bit to feel the increase. Apparently it's an adaptive tune that gives you more power after driving it hard for a few pulls.

I can also confirm that the tune makes a difference. Immediately I could tell the car pulled much harder than it did with the stock tune (P31 here as well).
