we all know this. I'm planning to use the tuner for the mileage tune and it's mileage coach, and also to monitor the engine vitals, especially boost. I'm still amazed the truck doesn't come with a boost gauge. Also being able to monitor plenty of other parameters just makes me feel better about knowing what's going on with the truck. Of course, occasionally I would put it on a high tune and floor it, but that isn't what I'm doing here.

And, I also know the dealer doesn't give a **** what my intentions are with the device. But they also have to prove that this is what specifically causes so and so problems. IMO using a mileage tune which may actually DECREASE available power will not cause an issue that ford says i have to pay for.

Most people know what they're getting into when plugging one of these in, but for those who don't - thanks for the warning.
