Recently purchased an 05 SRW 3500 auto (only 107k miles!!). I would like to increase fuel mileage with a budget of about $300 for a used programmer. Any suggestions as to which would help my diesel bill and still give me plenty of power for the horse trailers? I was looking at some Bully Dog Triple Dog GT (40420), but am having a hard time locating a used one. Another friend suggested a smarty. Thoughts?
Also, the truck needs bumpers. Ideas on where I can find a used set?
