Since I'm still N/A (stock DP), I'm trying to set up MS temporarily so I can learn how to tune.

Should I:

1) Just remove the narrowband from the stock DP and plug my Uego into it? My car w/ MS + WB doesn't need a NB sensor to run correctly, right? So this should work?

Or

2) Go get a bung welded on the stock DP?

If it's standalone you have no need at all for the NBO2. If parallel the stock ECU will throw a code but since it isn't controlling fuel/timing it doesn't matter.

From what I remember, the stock location for the WBO2 is ok since I'm stil N/A?

Am I remembering this correctly?

No. Well, probably not ok. My LC-1 says you have to mount the wideband say 3' from the head, or it will overheat. If you mount it closer, they say to build a heat sink to help cool the sensor. I put it in the stock location and said to hell with the narrow band, but I used a heat sink. Worked fine. Now it's 3' away with no heat sink. Still kickin.

Pat, weren't you supercharged when you had the LC-1 @ the stock location, though?

Nope, never finished the SC stuff. I had a 100 shot direct port though. Mount the sensor in stock location w/ no heat sink and you will kill it. And you won't be the first.

I ran the WB sensor in stock location without a heat sink for about 2500 miles with no issues. Its still going strong after about 4000 miles, has not required re-calibration a single time. The PNP timing map is pretty close to spot on for a n/a engine so it shouldn't really overheat. Just keep the EGT in control (not too lean or too rich).
