For one don't trust the stock boost gauge!!!! Get an analog boost gauge.
I recently replaced my O2 sensor I got it off ebay it's the real deal with the 
plugs, also it's made in Germany for only $55!! I don't think a bad O2 sensor
would affect boost loss like you're describing. Also unplugging the WGFV will
only give you about 6psi of boost. You want to try unplugging the
MFTS to see if the boost comes back. Chances are the N75(WGFV)
is bad. You can run the output test to see if it clicks.
