I'm not 100% on this, but it's my understanding that the factory o2 sensor remains in there as it's needed by the ecu ... Most people put a secondary wideband in to be used with the additional EM, but it's usually right behind the turbo in the DP ...

Yep the front 02 is not a standard wideband and is necessary for proper engine management. If you want to monitor A/F you have to add a separate wideband sensor in the manifold for your A/F gauge.
