That's the kinda disappointing thing about 5.0 mods. Due to the displacement and head design, anything other than a tune, sc, or turbo just seems to add power over 5000 rpm. While they don't appear to lose anything down low, the cj intake and gt cams seem to be worth about a 40 hp increase each.

I did see about 20 hp throughout my power band with my Kooks long tubes and race catted y pipe. But at about $1,300, the value isn't great in terms of cost per hp. But I do enjoy them

I didn't know the CJ intake was worth 40HP. That's impressive.

So for a extra grunt in daily driving, gears are the only things that will give more low speed feel on the Coyote. Converter would probably be a good option too. Has anyone seen much increase on true duals using the factory manifolds or even adding shorty headers?
