I'm a really new (5 days now!) Mercedes and SLK owner and was wondering if anyone made a tuner for these cars like the SCT unit I had for my Mustang? It's a 2004 230 K, really surprised me with the power, but like the man said, you can never have too much HP! I've never had any experience with plug in chips but that SCT tuner was really nice and easy to use once you had the tunes loaded in it. Thanks for any help or thoughts!
