What programmer would you use on a 2012 3500 Durand

[wheat]

Have a 2012 3500 crew cab dully. Gets about 14 mpg empty. I pull a 36 foot fifth wheel ,and it gets about 10.5 mpg. Just wondering if there was a good programmer out there that would help me with mpg ? I love my truck ,and can pull anything you put behind her

Programmer will not do much for fuel mileage unless you delete the emissions and lose the warranty. If your warranty is out then I say go for it! EFI live for dirtymax.
