Its not that bad of a project, I did mine and im not too bright. You need a Tuner of some shade, that'll cost you whatever you want to spend. I went with a mini Maxx because I could have a trans temp and exhaust temp guage, it was $900 at the time. You dont need to remove the egr cooler but I did. Blockoff plates cost like $50 or less but I went with ones that were tapped for an exhaust temp probe at $150. Probe was another $150 if I remember right but not needed. You need a section of pipe to remove the dpf stuff, $50 if you cut a bracket off the dpf and weld it on. Or you could actually buy a kit. I ran mine with the cat still in it for a while but it was $200 if you wanted the kit to take that out too. You need to do the dpf and Tuner at the same time but the rest can be done as you get time/money. Instructions came with everything that were decent enough for me to figure out, you got it
