Hi, Is it possible to reprogram Citroen C5 2.0HDI 140hp (original bin) with a bin file (again original) from 2.0HDI 163hp engine ?
Or, where can I find a place for download maps for different engines, but I want only maps that have been well tested, maps that are described what the changes do? I do not want maps from people who modified them for the first time in their life.

I should add that my C5 is from year 2009.
