They usually steal hp and the truck runs better without them, we tested them a while back on 4 different cars/SUV's on the dyno, they made no more power on two, and less power on the other two. :)

I can't believe people are still getting suckered into these things. Almost as bad as the "Tornado" fuel saver.

Just think of the concept for a second...and it's pretty clear it doesn't do anything, at least positively.
