Man. I'm jittery doing just above the speed limit as it is. Being a Park Ranger I know cops "see" our cars stand out more than others. Going 90 your just asking for trouble. I have an '06 (February). So far, 2 years next month and no trouble (knock on wood). Don't need the hassle.

 

some CAI you don't need a tune but to get the most performance you will need one

 

At 90mph, I don't hear any strange sound like you said. I don't have any idea. If you worry about it, take your car to the dealer. My car V6, auto. 2005.

 

and the dealer will tell you the exact thing i said in the first reply to the topic.

 

Yeah thanks I think we have cleared that up I need to slow down. But when I take it to the track in a couple weeks and hear this noise I want to know what it is.

Also I found a leaf in the filter compartment so that may be one reason, but I doubt it.

 

I can't hear anything over my stereo at 90mph.

 

The only time I have opened my stang up is late at night when like nobody is out. other then that i stick to the speed limit.

 

Cabbage, if you had a leaf in your MAF, I would suggest replacing your filter just to be safe in case anything else got in there. It very well could have been that leaf making the noise also.

I would not tell the dealer about the noise at 90, as they could void your warranty if they wanted to be an asshat about it.

It shouldn't matter how fast your going, just see what RPM's your running at 90 when the noise starts and then try and rev your engine to the same RPM range see if it happens again.

 

The K&N I have does not require a tune. I got a tune though because I felt like it :P

 

Whistle while you work,,,,,you're gonna get a ticket, youjerk,,,doo doo doo dee dee dee dee dum,,,just take it to the dealer and let themfix it,,,,then keep your foot out of it!
Just kiddin!
