Yup, that could be due to the SEGR or the GDE tune

Your setup (SEGR and GDE including the busted/disconnected FCV) sounds just like mine, except I haven't blocked the EGR tube. Did you find you were still getting some exhaust seepage even after the SEGR? Just wondering and sorry for the thread hijack, folks. If it matters, I concur with all previous statements that are backed by facts and weren't snide

Do you need both the SEGR and a GDE tune to eliminate the CEL's from a block off plate or just one of them?

Just one.

Yep, the SEGR ONLY take the place (electrically) of a normally operating EGR so that your ECU treats everything as if it's normal, but the EGR solenoid literally has no power to it (hence, stays closed). The EGR tune USUALLY keeps the EGR closed, too (see above), but also does other nice things to the fuel mgmt system etc.

I have both, but for different reasons, and as far as I can tell, they don't impact each other (again caveats with the reasoning for the occasional opening of the EGR from GDE notwithstanding).
