a wideband is just for tuning and dyno runs. you dont need to use it full time. you could but there's no point. you should keep the stock o2 sensor in full time and just use the wideband when tuning...
I would agree with this but..... when I relocated my relay box that is at the front passenger side of the engine bay, the wire for the ground of the fuel pump relay did not get a good connection. Because of this it never turned to 12V when the car saw boost. I noticed this while I was driving at ~8psi and looked down and saw 14.5 AFR! Needless to say I am glad I have it in there all the time plus since tuning is a constant thing you can do it is nice to be able to just do normal driving and mess with with fuel correction factors like air temp (DL), water temp etc.



Just my opinion...

Bob
