From what I have heard here Dan offered a money back guarantee to one person if not all if you so there wouldn't be anything to loose if he just happens to be wrong. There have only been two people in my dealings with diesel performance that have offered me a money back guarantee and I took both of them up one there offer. One paid off as it did what they promised. The other I felt didn't meet what was represented to me and I got my money back in full. Either way I was satisfied with both outcomes. I don't even have a PPE item on my vehicle so I certainly am not endorsing their products but any offer that will give a person the needed feeling if their money is wisely invested has zero to loose except about a hours time and a little shipping.
