Has anyone successfully tuned their C300 yet?
I've seen Chip Tuning (european website) has one but nothing on the US website.

It's extremely unlikely anyone is tuning their C300 while it's under warranty as this will void it.

I did 6 months ago. W206 4matic. I got the most aggresive racechip from europe. Took me a while to find tech that was willing to try installing because manual is for gti, so you had to figure it out. I run on map 7 all the time and it adds significantly big power. My butt dyno says around 70hp. And it sounds louder and the turbos spool up very aggresively(you hear it) got a dragy and got 4.9 sec 0-60. Lmk if you have more questions cus i was looking everywhere for info too but no avail.

Hey All, New member here and had the same question as Heloflyer68. Started following this thread wondering about tuning my everyday 2017 C300. I just picked it up, and it's pretty fun. I'm still hoping it has good overall reliability on the stock setup. For tuning, The ranges online are from Dinan to Brabus. some are overkill for me and some seem worthless. I like the car other than turbo lag and crappy transmission tuning. I just picked up these Quad Projector EURO AMG Style FULL LED, yet to be installed, and maybe the OEM brake upgrade. Its my 2nd Mercedes, my last was a GLE 53.
Thanks for any insight

hi I have a question are you located in the U.S. and if you are where did you purchase the tune I am looking to tune mine thank you!

bingbong206

yeah I was located in the US. I just purchased it through racechip website (the european one) make sure to mark the correct engine and 4matic configuration when ordering (although I think you get sent the same thing). But getting it installed is probably the harder part. The older models are easier to install, but this new 206 install was pretty tricky when I watched my shop do it. It took around 3 hours (figuring it out).

Hey how much was this tune, and where did you get it from?

Hey! When you say the install was difficult, do you have any details? Anything that would help others to buy and install would be awesome. Feel free to DM me and we can chat on the side.

Hey guys! I don’t check mbworlds too often but don’t be afrait to dm me on my instagram and I can help answer @keon_kim I also installed a vta dv from gfb from same shop so now my car sneezes after turbo spool lol

bingbong206

no clue wtf they did lol but they took off a lot of things and it was def more tricky than older model installs. I was just watching

So I reached out to Racechip and got the information I think folks are looking for. The installation is difficult because the plugs are in random places within the engine chassis and some are hard to get to. I attached the model specific guide which illustrates these hookup locations and should make a DIY install much easier. I also attached the User Manual.

I hit @keon_kim on Instagram, but am awaiting response there. I'll get to the bottom of this and be the guinea pig for us. But I hope this helps anyone who was looking for more data.
