How many horses did ya'll get from the superchip tuner on the 5.4L?? I was just curious if anyone has dyno tested it. Thanks everyone.

 

Also would I need a Gear Ratio change if I switched to 285/70/17s
I currently have the tires on, and I really cant tell a lot of difference but I was just wondering if It would be better for the Superchip if i geared down a little. Once again thanks alot
