Like the title states. Bought a semi bulit SR with tuned apexi power fc. Do you i need a o2 to drive the car properly or is the tuned power fc enough to make it run good. Seller told me that i didn't but want to make sure for its to late to get the senor

Thanks,
Jonathan

On the power fc theres an option to turn off o2 feedback so if it was already tuned then most likely it was tuned without it.So yea you should be able to drive it.

You should be able to drive it, but in reality it would be best to have a wideband in there feeding to a gauge in your interior at all times. That way you know if something starts going wrong (fuel pump, injector, vacuum leak, etc).
