Using NB sensor?

[nathans1987]

is it possibly to use a NB sensor accuratly? or is it worth the $400 odd for a decent WB AFR sensor. also does the sensor stay on the car? or do you take it off when done tuning?

Get a WBO2, they can be had for around $200.
NBO2's don.t cut it for WOT tuning.

Mine is permanently installed.

I don't trust NBO2's for tuning WOT either. WBO2's is the only way to go.
My LC-1's are permanently installed on both my vehicle's too...:)
