... If you remove all of the O2 sensors.
Monitoring the exhaust by the O2 sensors is the only way the engine management can adjust the mix and obtain the best performance.
What you don't need for performance are the cats and a second set of O2 sensors.
For track cars we remap the ECU to RoW specs which allow the user to remove the cats, the second set of o2 sensors and the secondary air injection pump.
