I have a 2004 f-150 reg. cab 4.6. I am going to 285/60R18 nitto grapplers from 265/60R18 BFG Long Trails. I expect severe mgp and power loss. I was wondering witch tuner (Edge, Superchips, Etc.) would give me the most power gain on 87 octane gas. Mostly for gaining some mpg's back.

Thanks,
Trent K

P.S. the only performance upgrade i have is an original 40 but i plan on adding an AF1 in the near future.

 

If you plan on adding an AF1 i would go with a stage 1 pachage from troyer. By far the best tuning as it is a custom tune. The pachage comes with the AF1 tuner and an exhast. As far as a canned tuner the edge is what most prefer and is quite a great addition to a truck.

 

Mikes' custom tunes are the way to go IMO *
