what is the best programmer for a 2002 4.6? i need to know some facts please, dyno numbers would be really nice thanks

 

A programmer for a 4.6.. well you won't see a big gain at all.. 5.4, yes.

Chances are your not going to get any dyno sheets just from a guy with a Programmer, CAI, Exhaust... because well your looking at a small hp gain...

Your probably looking at 10-15hp gain MAYBE... My buddy had an EDGE EVO on his 4.6, Which I think is the best programmer for our trucks. It didn't give it much performance gain at all.. with the small 4.6 you just don't get much performance.. so don't expect anything crazy.

If you want 1, I'd still say EDGE EVO..
