Which of the listed (programmers, tuner, or chip) is the best? As far as giving me the most horsepower. I understand there are lots of post about this but no post actually states which is best. Looking to get more speed and power.


2010 Ford F150 Fx2 5.4L with k&n air intake

 

You need a tune that incorporates that intake. So a Diablo or a custom tune in an SCT.

 

Let me know if you have any specific questions regarding our tools for the 2010 F150 model.

Thanks
