Been emailing spartan, told me today that they have 100 units in stock and have no clue whats going to happen once they are all gone, for the dpf delete and tuner set up, might just have to get my set up a little earlier. My warranty isn't through the manufacturer, some third party set up and it is a very limited warranty, found this out when I had my trans temp sensor go bad. So even if I did the set up, it might not affect much on what is covered. The biggest problem for me is that it would take about 4 years to pay for itself since I don't drive the truck much, in another year and a half I will be driving it more since I will be going to the U, and hopefully soon I will be towing my blazer around, so that would all help out with having it pay for it self.
