Has anyone out there successfully increased the power of there 200 with a remap or control box? I've contacted several tuning shops with varying replies - some happy to offer "chips" or rolling road remaps or control boxes but others,notably GAD tuning not tuning this engine. Most worrying was GAD's response to my enquiry saying they did not tune this engine as it was,in their words,"a weak engine" without elaborating on their statement. I have tried to get them to say what areas the engine is weak without any success ie.no reply to emails! Obviously I don't' want to create problems for myself by remapping somewhere else. Brabus are quite happy to add 20 BHP with no mods other than a control box and 40BHP with extra cooling so they must be happy the basic engine will take the strain. I understand this engine has been around a number of years in various guises so I would have thought Mercedes would have sorted out any "weak" areas. Any advice will be appreciated.
