Oxygen sencor nitous cut out kit?

Any one know of a kit that is kind of like the MSD rpm activated switch that is the same kind of idea but for exhaust O2?
I'm looking for a lean cut out of some kind for nitrous oxide.

I have never heard of anything like that.
The stock O2's arent accurate enough anyway.and i dont believe they are used in WOT.
Just get the fuel pressure safety switch and use that.
