On stock boost/power levels there is little or no gains from the AFE intake, that is a fact. With elevated boost/power levels time after time on the dyno we continue to see gains with the AFE intakes(n54 or N55). We wouldn't be running these intakes on our shop cars if they didn't make any power, not even if they are free. I do agree the power gains aren't close to what AFE is claiming, but the gains are definitely there.
