OK I searched, but I ahve not yet found..

I have read a ton regarding the issues of soot, egr, map etc etc if I do a GDE tune (probably eco) do have to or should I still do a SEGR mod?

no. The eco tune doesnt entirely eliminate use of the EGR, but it puts it to the lowest amount possibly used and it pretty much gets rid of all of the issues the EGR soot causes.
