You realize this is the body and suspension section, right?
X2 on getting Spartan
or SCT now and running DPF-ON tunes, depending on what you're going to run later. If you're tight on cash (probably your reasoning here), look for a used programmer for the truck. I sold a DiabloSport for these trucks for $250 I think. If you look around, you'll find something to get you by. But don't be surprised if the truck goes into Regen a lot more often due to the increase in smoke/soot. Might cost you more money in the long run if you run it long enough to mess up your DPF.
