I did try searching because I am sure its out there but I couldnt find it. I installed an Air Force 1 CAI on my 04 5.4 scab. Will this cause any problems with it running too lean? Or will the computer compensate for that. I have no other mods exept 285/70/17s yet.
Thanks for any help

 

you run a good chance of a lean issue specially with the 04 i would play the safe card and get a tuner with custom tunes to compensate for the mod/mods plus you will get the most out of your bolt on mods with a tuner too!!

 

Does the 04 typically run lean? What should I look for if it is running lean and what will I screw up if it is?
