I would stay away from them. Not to well liked in the diesel sites. Big claims, but can't back them up. More $ than other, better products out there. Wish I could find the picture where they had a display at a SEMA show. They had a banner advertising products for the "Cummings" diesel. Can't even spell the name for the product.
