The reason you see more negative about that particular tuner here than you do on DP is because some of the people in power here have a problem with him for one reason or another. Anyone who is unpopular is frequently brought up in a negative light. I did run the infamous flexy rods that he sold. I have spent a lot of money fixing it correctly, but we came to an agreement we both felt was fair. The compensation I got did not cover all my epxenses, but I take partial blame for running an unproven product. I gambled and lost; now I'm over it. It's not the first time, and I'm sure it won't be the last. In the end, I learned a valuable lesson that I will never forget.
Furthermore, I'll come right out and say that I'm not totally convinced that the tables in question are what caused the failure. I'm sure there are a lot of people that have run the tune being blamed without issue, but now all of a sudden it must be removed immediately because of imminent danger. Kind of reminds me of all the people that get all upset and worried about things like swine flu. People get sick, and parts break. Sometimes it just happens.
In the end, people recommend tuning they've had good luck with and usually don't recommend what they've had problems with. The only tuner I've ever recommended is IdahoRob because I have ran some of his tunes, and I know they work. I don't run anyone elses tunes because I refuse to pay for something I can do myself. If a "professional tuner" wants to tune my truck, I'll pay for the tune if he can make my truck faster than I can, but I doubt anyone is going to take that bet as I have a lot more free time to spend on logging and tuning than someone who runs a tuning business.
