Disable stock O2 sensor?

Is the stock narrow band O2 sensor needed with s200b or can it be disabled. The car is dyno tuned with a wideband only. No street tuning at all. This might be a noob question, but it's an honest question. I guess i figure since it's a narrow band and the tuner is making all the fuel adjustments. The stock O2 would just do nothing but confuse or get in the way of daily driving. But i could be totally wrong

Please help me out on this. Thanks

Once the tuning is finished, put the stock o2 sensor back in and run the car in closed-loop. This will help with part-throttle, and gas mileage.

anyone else care to back this up

I just like to have more than one person agree on one thing, so please don't take offense

when properly tuned, the car should be put in closed loop and it will run better and be more efficient.
