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?

I know people who have them and they do work. They give you more
options than the tow button. They actually control the engine rather
that the shift points.

I'll check back in a couple years when the warranty expires. I hadn't realized I had a five year
warranty. Thought it was three or 36K.
