You can let reprogramm your chip oder build in ...
front of the chip a seperate additional box. These 2 types of chip-tuning are possible in germany.<br> In germany the speed of the clk ist automaticly stopped by reaching 250km/h. So I think the best is to build an additional box in front of the chip, to switch off this limit. You can put this box away for visits by your mercedes dealer or any guarantee - things.<br> So first you have to think about, what you want to change. If you send your email to me, I will give you a list of Tuner in germany, who make this.<br> Regards - Manfred
