Default O2 sensor after Big Honkers/VFCIII aand air intake?

My apologies if this subject was already posted before....

I own a 2010 vision 8 ball. I have the big honkers (Ness), VFCIII and both front/plate air filter performance.

Should the O2 sensors be left connected or should i disconnect them?

My 'certified' Victory tech is saying that there is no need to disconnect them as the VFCIII overwrite the O2 sensors.

I am kinda confused since i've read different opinion regarding this?

So can someone knowledgeable can answer the question once and for all? :P

Thanks fellaz
Cheers!

I have the same thing. Except a PC5. Look at the discussion right next to this one about this. It is tagged PC5 on vision or any bike.

Follow the two links in it posted by other people. Basically yes disconnect them.

o2 MUST be disconected, or the VFC, and the ECM will go into conflict

I'm not an asshole...I just type that way

Good. Real good. Deep rumble. Then when you get on it it sounds like a muscle drag bike. I love them

Yea at an idle the don't. They are deep but not that powerful of a soundwave. Once some throttle is given they definally can. I can actually feel a rumble in my chest during deceleration.
