I cut open my air box and added a K&N air filter. It sounds awsome when you step on it.

RE: Free Horsepower mod
OK, this is just something I heard online at another forum...
"The stock Mustang GT comes with three stock tunes...the normal, default one (the one that is overwritten on a re-flash, and stored in the re-writeable memory), the limp-mode one which is extremely restrictive (stored in read-only memory), and one hidden, "performance/diagnostic" tune (also stored in read-only memory) that they use to push the car to its limits to test it before delivery to the dealerships.This tune includes a 7k rpm redline, much more aggressive timing, and very quick/firm shifts for autos to stress the tranny. Again, it is used to dyno and/or test the Mustang before it leaves the factory to stress out the drivetrain, tranny, etc. and is tuned for maximum power (don't know if it's 93, 91, 89, or 87 octane). Also, since they use this tune to test the car, that is why brand new Mustangs usually have the computer/car reporting such poor gas mileage the first few tanks because it is used to this powerful tune."
Anyways, I'd love if someone can confirm or deny this rumor I heard. There is *supposedly* a rumor going around about how to activate this tune on other forums, some say it takes a tuner to activate it and some say you can activate it with just weird combos (like the seatbelt warning light disable trick). Can anyone shed any light on this?

I cut all four sides of the airbox with a dremel. Only solid part left is the top. The rest of it looks like a frame. No dyno tune just the 87 tune that came with the tuner.

Which tuner (SCT, Diablo, etc)? How long have you been running this set-up? How do you know your not running lean by altering the amount of air intake?

RE: Free Horsepower mod
You could always get some piping and route that to the intake ... sort of like a ram air effect. I didn't do it to my stang but my boy and I did it to his car and there was a noticeable difference. He has a turbo though so I'm sure that they played a part but either way the car seemed faster and temper's dropped.
