Good comments here, but I will try and clear a few things up. I agree there are some chip scammers out there like there is with everything you buy, some honest some not. I am fortunate to live in Newport Pagnell which is only 1 1/2 miles from MB (UK) Head Office in Milton Keynes, and therefore over time through my work have got to know a lot of their staff including senior engineers. The chip issue intrigued me having heard of some very positive comments by other MB owners, so I thought I would ask a few questions with ‘the people in the know’.
I was told by their engineers that if you want a chip that works, is proven, and is made to the required standard, then buy a Race Chip. No surprise then that they are made in Germany!? A lot of the guys who own their own Merc and do not drive a company one have this chip fitted. They also say the best notable gains are to be had from diesel engines.
I also asked the question about what effect it would have on engine components and of course my warranty. I am told that the engines are produced and tested to allow for a variation of mapping scenarios which give much increased power, but are effectively tuned down to suit various legislations in other countries, and most notably where the tax is defined by the Kw output. It is far too costly production wise to map every car specific to a country of shipment and legislation. There is of course a warranty issue if MB wants to be anal about it, but I am told its totally untraceable when removed for servicing etc. Also, you should ALWAYS tell your insurance company that you have one. I did and the premium remained the same J
Had mine fitted now for a few days with no issues at all...just a big smile. As for fuel consumption, yes you will use more if you always have your foot to the floor but driven sensibly you need less throttle and thus save on fuel. At the moment I do not have any figures, but when I do I will post them.
If anyone out there buys one for the SLK 250 then I will pass on the settings I currently use which are fine for me and seem to work very well.
