Running RICHHH....

This started after the SOC02 track event. The O2 sensor never sweeps back and forth and I get 16 MPG's! It just sticks around last bar stoich or one bar rich throughout entire rev range. It does move to 3 bars rich when boosting, and it does go into the lean area when I take my foot off of the gas, but that's the only time it goes lean!
I checked the AMM and it's still set around 200 Ohms, I replaced the O2 sensor this weekend, checked the engine temp sensor, and looked for any vacuum leaks. Eventhing looks good.
The fuel pressure has not changed at all.
I'm thinking that the ECU is messed up?
Any other ideas?
