Question ECU tune

Hey guys im sorry if i posted this in the wrong thread or wrong part of the forum im new to this.
My question was i have a 2014 c300 4matic sport and i been on rentech and brabus and eurocharged but i couldnt find a ecu chip tune. I have found 20hp with faster throttle for 600+$ but to me that is definetily not worth it! Does anybody have a link to a reputable site with dyno proven better ecu upgrade?

Just recently bought Eurocharged. Supposedly OE and Eurocharged have same gains, and clearly they are the most popular.

Since 2014 is turbo (right? Or am I wrong...) it is more expensive...

http://www.oetuning.com/products/mer...nz/c-class/300

Keep in mind OE requires you to buy tuner as well, so pricing will be same. Euro includes tuner in price.

It might just be the tuned stock version [has nothing to do with aftermarket tune]

So yea then about $600 I think. I would contact eurocharged, idk why it says 2012+ then. Data sheets are for facelift c350...

Don't underestimate increased throttle response! I had mine tuned by Eurocharged a few months ago, and I'm still amazed at how the throttle lag is gone. Sometimes you're just cruising down the road and you get the itch to get thrown back in your seat a little, so you give it some gas and you instantly go with more umph than you remember having. It still catches me by surprise sometimes. So much more fun to zip around town now.

I remember doing this to my MK3 Jetta. Not only it gave me a little more hp gain but it ran so much smoother like a new car, even idle beautifully. what I needed to do was remove my ECU from the jetta open her up, replace on board cpu chip fairly easy, & plug it back up. the setup cost me $200.00... $600 is a little steep for me. but I will keep an eye out if they have any specials like Adi-Benz got.

If you have the m276 V6 engine, your gains could be up to 330 hp.

Anyone who says $600 is too much for a tune is most likely not on the M276 platform (which the OP is).

On the C300 'version' of the m276 v6 engine this has been debated but I have yet to see a dyno proving this.

It makes sense to me that it is possible, no different than the various tunes/versions of the C63 engine (stock/p30/p31/507 versions) all making the same or similar power after an ECU tune.

Would like to see dyno graphs or feedback from a C300 owner documenting the gains.

The m276 c300 is a detuned c350 engine I'm pretty sure. So the tune would boost it up to approx the same level as the c350 tuned right?

I'm not even 70% sure but just throwing that out there.

That is my thought, but no tuner has been able to provide a dyno sheet or examples when asked, but they all say it.

Intuitively it makes sense to me, but not sure if I want to spend $700 on a hunch.
