Mark,Mercedes

Just a quick note to say that I fitted the tunit over the weekend and the results are excellent. The smooth quality original characteristics have not altered at all, however the acceleration is much stronger and longer I have not been on the motorway yet so not sure what the MPG will be like Thanks for all your help

Very impressed. I liked it that much I even wrote a review of it in the Volkwagen Driver magazine. April and May issues 2008.
