Tune Required For CAI 2004 Mustang GT

I was just wondering if a tune is required when running a S&B CAI on a 2004 Mustang GT 4.6 L. I realize a CAI alone doesn't add much power. Just want to make sure it won't cause car to run lean. Thanks in advance for your input.

On 96-04 cars, a tune is not necessary to run a CAI in 99.9% of situations. I've seen certain cars, but mostly Mach 1's and Bullitts that will get near a dangerous lean condition with the CAI, but can typically be corrected by just changing the orientation of the MAF. I've never seen that problem in the GT though, as the GT stock tune is pig rich to begin with and can benefit from being a little leaner.

only reason i'd get a tune if i were you, wouldn't be for the CAI, but if you had an auto. Automatics benefit from getting tunes because it firms up and changes the shift points of the transmission. Makes it have a whole new feel to it.

The S&B CAI only adds about 40% more airflow and according to S&B does not really require a tune. I have one on my Mustang and have run it stock airbox and with KN selected on a strategy tune. There is a little bit of difference with a tune but not enough to worry about getting a tune just for the S&B CAI. The KN does not require a tune either. Brenspeed wrote my tune to include the S&B along with my other mods but I quit using it since the tune is affected by temperature changes and does not compensate for them. A tune will give more power with the CAI but it is not worth the cost of a tuner.

You have a 2007........ Nothing that you've experienced even comes close to comparing to a 2004, their processors are totally different animals and react 100% differently to mild mods like a CAI.
