Hey guys. So i have a 2017 c43 and its getting up there in km. Its at 130,xxx. Never had a tune or any upgrades. Anyone else out there with tunes that are at 100k+? Any problems or concerns? Also can still be reccomended at all being high in km to get a tune? I plan to get a tune by EC toronto as they are very highly recommend by many of my friends and

Hi in terms of problems it all depends on how you take care of your car. I have had eurocharged tune for roughly half a year now and have not had any problems. With that said, I would go for the Renntech tune. Im at 76,000miles but also pushing a car built for 361 horsepower to 500+ is something not made for your car. I am expecting to start encountering problems at some point but that is the name of the game when it comes to tuning. Renntech is 414hp I believe which is not as explosive as eurocharged but if you are looking for reliability this is probably your best bet. If you are worried about reliability regardless of how many miles your car has you are increasing chances of engine knock, misfires, etc. Brabus or renntech is probably the least risky for your car as these are famous tuning companies specifically for Mercedes c43 and they don't push your car past its limits.
