The one thing the aftermarket intakes are doing that the stock isnt is they enlarge the MAF section a tad that tricks the ECU into adding more fuel or something like that.

The factory intakes are very efficient and are effectively cold air intakes since they source air from the same place that the G3s and Injens do (outside the engine compartment). They flow very well and are only a restriction after about 7,000 RPM.

True dat and above 7K rpms we are probably on the the down swing with power and should be shifting by then. I need to find out when the 7AT starts to loose power in each gear.

Any idea what the MAF numbers are trying to tell my dumb aZZ while Im logging them? Im not sure how to interpet the numbers.
