Assuming you mean Lambda (o2) sensors.

 

Yes, you can unplug them. Car will run a stock AFM. In reality it means you will just run a little rich.

Unplugging O2 sensors pegs them at 0.31V/0.32V. ECU doesn't run a stock AFR (there's no such thing). Unplugging O2 sensors will simply add a fixed duration to the basic pulsewidth calculated in the main fuelling map, which consists of 256 load sites where fuel is calculated based on load & RPM. So basically it runs richer than 14.7:1 AFR where O2 feedback is activated, which in turn depends on the map you're running, generally idle & cruise (light load). No effect "on boost".

 

But yeah, just unplug 'em. Lots of threads about this if you search :)
