ok heres the deal i have an 05 lariat 4x4 5.4L. i recently put 35" tires on it and my power and mpg went down the tube. what can i do thats affordable to get a few more horses and better gas mileage? i know there are a lot of "chips" out there so what brand is the best for the money and shows the best results?

 

i have an edge. i went from tires that weigh 40 pounds the nearly 60 pounds apiece and without the chip on i could really feel a difference, but the edge makes it almost unnoticeable. the gryphon is basically an edge but upgraded for your individual truck and any mods u have on it. if you have stuff like a CAI or exhaust, then id suggest the gryphon as its worth the money from what ive heard from others. also i noticed u have an 05 year truck, which are known to run lean if you put a CAI in your truck, and the gryphon will take care of this for you. but for me the edge does the job just fine
