So far on my 2011 mustang V6 I have a k and n cai, a bbk 73mm throttle body, and bbk shorty headers. They say for headers alone you should get a tune but is it really worth it? The video is only with a cai
You don't really need a tune. It will be fine without it. But get a handheld not a custom tune. The handheld you can get free tunes for life and tune for future mods and A LOT cheaper. A tune is a great mod.
