CLKCLK

I also post this in CLK 208, 209, but it seems no response. Hope someone can give me some info.

I remember that I do read in here somewhere that someone is having an ECU upgrade for $350 something. I am interested in upgrading my ECU and wonder if someone here has already done so.

I would like to know where to do it? How much does it cost? And how much performance gain? Or if one knows about the ECU thread that I mentioned above, please post me the link.

Thanks!
