Pwr Cut at 6800rpm Full Boost
Maybe some of you have better clues than me.. I am getting pwr cuts from 6800rpm to 7000rpm. This happen only while car is under boost (5psi). During the pwr cut, I can see the boost pressure remains stable at 5psi. After the motor gotten itself over 7000, it regain full smooth pwr till I let go of the throttle. When I push it w/o the boost, it will spin pass 6800 to 7000 smoothly.
The motor max boost is 5psi. I know I have enough fuel as tailpipe emission test shown rich. I have new fuel pump, stock injectors, stock fuel pressure, RX7.com exhausts, stock airbox, fuel cut defender, all engine electronic are working (as far as I can tell...) This is not a ported motor.
Any idea what else I should check?

The AF gauge shown I'm at full rich but I don't trust it. Once I'm over 7000rpm, I get all my power back so I have doubt its fuel starvation. Motor push hard right into 8000+rpm
