Do you need O2 sensors w/ SD?

Running HP tuners 2 bar SD, fabbing up a new setup for turbo. Do you need any O2 sensors in the exhaust at all?

You can tune it strictly off a wideband but I prefer to have the narrowbands in it for idle/part throttle tuning.

So do you need them or not? are they used in a SD tune? Im not worried about them for tuning it. Im wondering if they are needed with SD.

they have nothing to do with speed density, they are used for closed loop fuel control on the car. You can run CLSD, OLSD, CLMAF (OEM), or OLMAF...

ok. I might be an idiot on this subject.... so I should put O2 bungs and run the 2 front ones on my turbo setup then? I had them on my old one, but i never used them to tune anything, I just used the WB.
