No cats here, ANd according to the manufacturer MAF adjusts fuel based on what it sees coming in. That is the whole basis for the dry system. The instructions state, "Spraying cold nitrous across the MAF will cause a significant increase in fuel delivery and the N2O will allow you to burn it." Their whole claim to safety with this system is the direction of the dry nozzle and how it hits the MAF. This is also how you get a little HP out of the CAI. Cooler air, More air, MAF adds fuel.

Edit: and just for the record, (and I know others have already disagreed on this), but they also state the O2 sensors play a role in fuel delivery too. like in addition to the MAF monitoring what is coming in, the o2 sensors monito what is going out. So 2 measures of air coming in to add fuel by stock fuel system, and the N20 to burn it. Makes sense to me.
