Need advice on ECU upgrade/chip
I was wondering how many of you have had an ECU upgrade and what kind of gains you've seen. Also, how much did you pay and from who? I am heavily considering doing it. I was wondering if Mercedes can get you an ECU upgrade. My dad knows the parts manager at our local dealer and he said he was going to see if he can get me one. Do you think it's worth it?
