Default Do I need the narrowband with a parallel MS?

I am running MS in parallel with the stock ECU. I currently have the stock narrow band. I have an AEM UEGO that I plan to install. Do I need to keep the stock narrowband O2 and have a new bung welded in? Will it run fine if I just remove it and put the wideband its place and do the mod to the msq I saw on here?

you dont need it, but the ecu might throw a CEL.

How close is the current bung to your turbo? If closer than 18" I would put another bung in further downstream

Wherever the Greddy DP puts it. I will see how far away it is, I didn't even think about that. I may just have a new bung welded in.
