On the 05-2010 mustang GT's and CAI that doesn't require a tune won't give you much if any power (ie the K&N CAI)
I saw 281 RWHP on a mostly stock (only had a K&N CAI and Flowmaster axle backs) 2007 GT.
(youtube clip)
to that page and click on the video. Even with a tune and "racer" CAI my car somehow put more power down.
To properly compare mods you need to test them on the same dyno, same area, and same weather.
Are you sure that that 281 isn't crank corrected? and the americanmuscle isn't RWHP?
the insert is removed on the street and race model of the C&L when you plan to put a tune on and the race one really isn't much over the street.
