The cheapest way is to un-plug the EGR valve. This will get you maybe 2 to 3 MPG's over stock. You will get a CEL but this will not cause you any issues with the truck. I ran this way for almost a year before I deleted and spent $$ for a Smarty and a 5" TBE.

I would also use electrical tape around the openings of the connections. Tape off the openings to prevent moisture from entering the pin connections.
