How would I know if my Mustang has a tune or whatever???

 

That depends...If the radios on or not ...

Thats a good question...Unless you have a dyno available..or know of a shop that has one. would be the best way to findout...
Since you bought it used jerry...

 

There are many tunes about Mustangs.

Here's a link :10 Songs About the Ford Mustang

Black Sunshine by White Zombie is my favorite...

 

HaHa, seriously I was doing some research on the C&L CAI on it and they come with tunes and without.

You have to admit Jerry, you left the door wide open on that one.

I would assume (hate doing that) if your CAI included tuning there would be a 'Performance Tuned By' plaque somewhere on the vehicle. I would also think they would have included the tuner with the vehicle. That is, unless the previous owner had a friend or two that also had the same CAI on their 'stang...but the tuner might be locked to the VIN.

 

Well way back when I owned my 05 V-6 the C&L CAI would only work with a tune. I'm not 100% sure with the 4.6L. As I recall the K & N was the only CAI for the Mustang that did not require a tune. The tuner usually was a Diablo tuner (that is the one I had) or a SCT tuner.
