Diesel Performance Unlimited, good or bad?

If you have worked with these guys before I would like to know what you thought of their products and service. I had heard they have turbos and injectors available for the 03 so I gave the Pasco shop a call and they told me they could put in 100 hp injectors along with the ez and I wouldn't have any egt problems. Burn more fuel over the same time in the same space without any increased cooling and it seems to me your going to have more heat. Anyways comments from those who have worked with them would be appreciated. Thanks.
