I didn't read the whole thread, just skimmed after page 1, but is anyone looking at A/F compared to HP/TQ? It's VERY clear that the ones making the most power are the ones leaning out up top, and the ones making the least power are the ones running pig rich up top. The AirRaid is off the scale lower than 10:1 for a good portion of the run!

These results are good to see how a bone stock car will react, but if you want the most out of an intake I would get the one that flows the most (regardless of power on a stock tune) and get tuned to match the flow of the intake. I bet with a tune you would see the AFe or AirRaid make the most power overall. I doubt you would see much gain at all with a tune on the Injen since that secondary tube is already leaning out the top end for you.
