ECU for Mercedes C300


New member
Hello everyone,

I'm looking for an ECU tune Mercedes c300 2015 but I don't really know a lot of things of ECU except that it helps your fuel car, boost your HP and help you switch gear etc...
If anyone has tried one or have a friend that bought one in a shop or online I would like to get it too :) (I prefer to get it in person in a store than online)

Thanks guys!
