I put a brute force intake on my 00 5.9 4X4 and i went from GPS checked mileage at 13-14 mpg......once I installed I went to 18 mpg checked and confirmed by GPS so I give the AEM brute force two thumbs up!!!!!!!!

 

4-5 mpg jump just from an intake. hmm.

 

Please post a picture seems too good to be true. Id like to see how the design is and how it looks on your rig. But if you are getting 18mpg you really are doing good!

I only get 13-14 downhill with a tailwind

 

I have looked at that setup, its no different than K&N, try a MPG vs miles driven test (non-GPS), may find out GPS isnt all its cracked up to be..........
