Has anyone tried the $ 69.00 GFChip on a F150 4.6 ? If so, did it make any difference ?

I have one. The truck does run and idle smoother. I have noticed that it has more power, it doesn't downshift on hills as much. As far as fuel mileage goes I haven't driven the 100 miles they say it takes to completely set its program. So it is still a wait and see at this point.

Thanks for the reply RebColonel - Just ordered one on Friday. If it only does what yours has it will be worth the money.

Looks like a resistor in a box scam "chip" to me. All they do is richen your fuel mixture up.

Quick google search confirms. If you ever have a question about a product, search product name and then "scam" and read what comes up.
