As a new member, thought my experience with re-mapping might be of use.
My 2007, Ducatto 100 was remapped some months ago, by a mobile technician. The van had covered only 25,000 miles in campervan form. I was offered three options, a) for economy b) for economy and performance, and c)outright performance. I chose (b), and immediately felt increase in performance, and economy according to the computer, BUT the clutch slipped on the first steep hill encountered. I then had the ECU tweeked back to option (a), and although the clutch seemed normal most of the time, it slipped at 50mph in fifth gear, with the vehicle fully loaded.
So......I had it put back to the makers settings, and all is now well. I was only charged an "admin fee" of £40 or so.
The moral of the story.....check first with someone who has had their IDENTICAL vehicle modified, OR fit a stronger clutch!!
Finally, if the clutch hadn't shown it's displeasure, one wonders what else might have gone instead!!
