The following info needs to be collected for a more detailed intake shoot out.
MAF g/s airflow vs. load/rpm - how much air does each intake flow
Wideband AFR vs. load - how each affects the stock ECU tune
Short term and long term fuel trims changes - how the stock ECU tune is compensating for air flow changes
IAT(intake air temp) from idle to moving @ 40/70mph - how each reacts to air temperature which affects the ECU tune

I posted a lot of this information (minus the fuel trim stuff) in my roto mold shootout thread.

I will say, that the stock tune did an amazing job at adjusting for the aFe since it held an identical AFR curve to the stock intake.
I'm going to do IAT readings between the aFe and the AIRAID as soon as we get a dry day around here. LOL. I have them in different logs taken on different days, but I want to compare them on the same day for the same temp.
