Hi guys I'm new to the forum, also new to the mercedes owner club, is there anyone the can help me, I would love to remap/chip my 2009 c220cdi amg sport, but I've been told it's not possible as mercedes have incripted the ecu stopping and remap, is this true? If it's not could you suggest where to take it?? I've also been told that if it's possible it would knacker my auto box. Is this true?? Many thanks guys
