I've been doing a little research and what to know what most people do

Do people use the stock bung location? and somehow integrate the wideband into the stock ecu to use for tuning and replacement of narrowband

or

Do people have a second bung added? keeping the wideband totally seperated just using for tuning purposes

 

The WB needs to be a ways downstream of the turbo, otherwise you'll overheat it. But it has to be pre-cat.

It also needs to be between 9 and 3 oclock, otherwise it can fill up with deposits. I'm not sure how big a deal this is in practice, though.

You can either keep the exisiting NB O2, or you can run a simulated NB O2 output to your ECU.

 

Kyle is correct. I tried the Greddy bung. Too much heat and/or pressure. Others report the same.

Sim NB signal seems to give me better idle, but I'm still not thrilled after hard cruising. Maybe it's still overheating in the midpipe.
