Air/ Fuel ratio Wideband on Carbed motor?

[USMC45]

First off here's a couple quick vids of the initial start up the other night.

It's a forged, dished pistons, H beam rods, 383 stroker with 9 to 1 compression. It's only gonna see about 6-8 psi of boost from the Vortech V3 supercharger on it. So my question is, do I need a Wideband? FAST makes one that does data logging and has (2) sensors for exhaust instead of (1) like the normal auto meter Wideband.

I also have a LS Turbo motor in my other truck and I know it's a must have in it but I have been told its not so important on Carbed motors.

Any help is greatly appreciated!
