I just bought an '05 Chevy 2500 with a 6.6. It has an Edge tuner EJC-1000A, K&N air intake, and a bigger exhaust (not sure what size). I am wanting to get better fuel mileage because when I drive home its 10hrs 600+ miles one way. I also want to get better towing out of it because I pull every now and then. I've heard talk about doing a "delete kit", but I'm not sure what that is. What do you all suggest? Also what are these two switches for next to the display? Thanks in advance.
