I don;t wanna spend $200 for something that's gonna tell me the same thing, that it's running rich under boost...
I would rather buy a VAFC so I could actually decrease the amount of fuel it's getting...
Thanks for the help,

A narrowband O2 sensor is worthless for tuning because by the time it reads what it does, the computer has already made adjustments. And it doesn't tell you how lean or rich it is running, so if you take too much fuel away, it could run so lean that it blows the motor.
You have already invested so much in the turbo, so why cheap out on tuning and risk a blown motor?
