I have a 05 FX 4 that i am thinking of adding a Cool Air intake. But I am also considering a Hypertech or supperchips tuner. Which would give the most MPG improvement for the money? I understand that both would be the way to go, but I want to start with the best option first.
The 5.4 has a flowmaster exhaust and a K & N filter at present.

Any info on this would be helpful.

Thanks.

Go talk to the folks at Troyer Performance and they will hook you up. They are able to answer all of your questions.

 

I did it all on mine.

Go with the tuner first.

 

Yeah, the tuner seems like the best way to go 1st. And then see how much more is needed. Thanks for the info.
