When I rev it up to say 3-4k rpm it instantly goes rich (10-11 AFR or more) with NO BOOST
So this happens with no load on the engine? Like sitting in the garage and blipping the throttle?

Stupid question but have you verified that this reading is correct and there is no issue with your detection equipment and O2 sensor placement?
