i dont care about cruising fuel economy on the car. i drive it to the track and home. And i really dont feel like having to wire in the O2 sensor and make the bung for it. it only take signal into account during closed loop, correct?

SureShot

Yup.

u will run alot richer with it not connected. the richer u run the less power u get.

i can tune for such a condition under full throttle. but for ease doing things. I really dont see the point of putting the o2 back in.

i have never run a O2 even when my car was stock and it ran perfectly fine.

You don't need the O2 sensor for the car to run. It is ignored except in open-loop mode (cruising), so it does nothing on the track.

even without it, i still get over 20MPG on the highway in my NA

No, you will run slightly richer during cruise only. The difference in average fuel economy is small.
