Err... honestly I don't quite get the original question... although carbon monoxide and carbon dioxide are both existing in normal atmosphere, in most situation we only care about the oxygen to fuel ratio (or you may assume air consists of only oxygen and nitrogen for simplicity, and thus we care about the air to fuel ratio). But carbon monoxide ratio... !?

Yes the CO level is important for off idle performance of the car. It doesn't really affect anything after that. It won't make you go faster. You want it to be around 0.6% IIRC and that is measured before the cats. You need to find a shop with gas tester. This is usually done the same time as syncing the throttle bodies.
