Bill,
Yeah, I read the installation article, and it looks easy, but when you have to tap into factory wires, it's kinda intimidating. But, I need to get one because my speedometer, odometer and trip meter are all outta calibration...so I have no choice...unless there is some other gadget out there that does the same job. Hypertech has a programmer which taps into the factory computer, but it's only for chevys and fords!!!
