I can't give you an actual number, but O2 sensors are what are responsible for changing the fuel...rich or lean. So it can swing the fuel a lot.

Are you sure your wideband is showing the same numbers as the stock O2s?

I think that piggyback system sounds like more trouble than it's worth vs just getting an actual tune.


I will admit the issues I was having were caused by user error. Once the MAP settings were corrected things are going much better. The AFR is leveling out in how much it fluctuates.

Your second comment is what I am not sure about. The AFR is showing lean, but the plugs have been reading good (tan). I just don't want to blow the motor from being too lean. I can tell the factory computer is what is pulling it to the lean side now the O2 are connected.
