I recently got the DiabloSport Predator programmer from a friend, I'm thinking of installing it on my F550. My question is does anyone have one installed on their 6.4 and how do you like it? My dump is pretty slow loaded down with the enclosed and a load in the bed, it also gets in my opinion horrible millage for a diesel. Do I need an exhaust and an intake to use this programmer? I don't want to hevily modify my work truck. The thing is only used for work and is driven by my two guys 6 days a week. I got the programmer free for doing some work.
