Hi all, well I’m keeping my ‘04 SLK320 Special Edition, only being 24 from a sale and acquisition on an ‘06 SLK55, there were just to many people saying it’s too nice to sell. It’s booked in now for high quality respray, original split rim alloys refurbed, underbody rustproofing and service. So my question is what’s the best way to get 25-30bhp and is achievable relatively painlessly. I’ve read that the exhausts are restricted so my first thoughts are new custom made stainless exhaust with maybe Magnaflow boxes, then ensuring plugs are good (replacing if necessary) and a proper rolling road dyno tune. Anymore thoughts peeps?
