Help gears or chip???
I got a 2004 f150 STX 4.6 with a 6in lift and 35in tires. Which is better to get dif. gears or a chip??i want something with better gas and more power. i will be doin highway driving.
The problem with doing the gears and than the tuner is that your speedometer is going to be WAY off along with your transmission shifting whack. . seems like it'd do more harm than just adding bigger tires. Thats just my opinion anyways. .
