Tuning a clk320 at low cost

[Marv]

Any ideas about a tuning program for my clk320 (german spec)?
A specialists told me that with 500 $ i could increase horsepower to 250, by working on the exhaust, putting 12 gold spark plugs, changing the software from stock to brabus stage 2 performance one.

Welcome to Benzworld Marv-

Umm, I'll try to be nice. First, you have a 320 (like me) so you wont win any trophys at Hockenheim no matter what. Putting $500 bucks in her for a questionable upgrade would be a waste imho. Spend it on visuals and roll slow. Buy a used aftermarket exhaust system for that money and sound cool.
