Please help. Can someone explain how maf flow rate works in atap. As I see it, it is simply a measure of how much air is going through the maf and into the intake. But what is the correlation to other variables like HP, O2's, ect. I would think the higher the maf flow rate the higher the horse power and lower the o2's would go. What should I expect my Maf flow rate to be and what would that indicate about my car?

MAF flowrate is as you surmised, the massflow of air into the engine. As it increases at a given rpm hp/torque at that rpm should increase. As it increases with rpm, hp should increase - though torque may or may not.
It doesn't have a correlation with o2's. Infact under given driving conditions the o2 readings should stay the same (or in the same range) - as the computer increases the fuel based on the maf rate - to maintain a constant a/f ratio (which correlates with o2 readings). You should only see significant swings if your desired a/f changes (like at WOT, etc.).
