Any input for the best chip for a 04 with a 5.4L to get good gas milage.

 

its a truck...not an economy car...but get either a superchips, SCT, or edge tuner for it

 

You won't see but maybe 1-2 mpg gains with a tune. It's more oriented for performance then mpg and you will affect your mpg more by how you drive. That being said, I do have SCT units for your year and engine, hit me up if interested.

 

I got 1mpg boost with my superchip cortex and a noticeable power boost
