I've been reading in my farm papers and magazines about a new product called the Workhorse, which claims to increase fuel mileage and power. It claims to be different than all the other computer "chips", and in fact claims that it is not. The website is www.888luvdiesel.com. Have any of you tried or know of someone who has tried one of these? I've read a lot of the articles in TDR on chips, but this sounds different. I know, if it were meant to be better for the engine, Cummins would have come out with it first! Any thoughts or input? It claims to have a 60 day money back guarantee on it, but I know that guarantees aren't always what they claim to be. Personally, I want all the mileage I can get at $3. 00 a gallon, and could care less about the "power". Let me know what you think.
