Does anyone know of any tuners besides RennTech working on mods for the CLK 63 Black Series. I'm not looking for engine tear down mods, just some bolt-ons such as exhaust, cats, ECU up-grades, air box/filter., etc. I had some Renntech parts on my CLK 55 and was not too impresses with the quality or performance. Any of you out there done anything to your Black Series yet?

Thanks,

 

We do have ECU tuning available.

 

Who did the program? Have you done any on Black Series yet? What kind of gains are you seeing? Does it eliminate 186mph speed limiter?Where are you located? Do you need my car or can I just pull the box and ship it to you?Lead-time and cost?

Thanks
