I have a Spartan tuner on my 6.4 powerstroke, it has been egr and dpf deleted with a s&b intake installed. I am trying every single tune on my Spartan and the best mpg I can get is 12.....help please!!!! love my truck but need better mpgs. I traded a 06 dodge dually that got 19 for this damn thing. I know it can get better...hell my 04 6.0 got 19.........!
Are those hand calced or are you going by the lie-o-meter? Unfortunately, a 6.4 will never get great mileage. One of the reasons is the emissions crap which you did remove. Weight of the truck, stingy heads (which means you have to run higher EBPs and boost), and compound turbos also don't help.
If you run a tune with aggressive timing (the 310 for example) and can resist the skinny pedal, you should get the best mileage.
