Actually, these things are also made for use with gas engines, but that's not my concern.

I'm wondering if anyone has used one of these. I'm hearing some good things about the results from a
neighbor who has put one on his Ford 250 diesel. He says that by reducing the power capabilities he
can improve the fuel performance capabilities.

Anyone used one?

Don't know about this brand but this technology has been around for
Diesel for a while and from what I hear is pretty solid so far. We are
even using it on the race bikes now, that's how far it's come. If I
were you, I would do the research, read the reviews, and pick one...
