every thing you just said is right on track!!!! :agree: oh its a 6.4:icon_ford:Number 1, there is no such thing as a 6.3l powerstroke. Its the 6.4l
Your not going to get any miliege benefits unless you get rid of the DPF.
Running a programmer and keeping the DPF is going to cause for alot of extra Soot in the DPF, and which will end up causing it to need to be replaced, and they are NOT CHEAP!! Not to mention you will get just bout zero benefits, MPG wise, running a programmer with the DPF still on.
If you don't wanna do the DPF delete, your better off to just keep the truck stock.:thumb:
Is this hand calculated?well you dont HAVE to remove the DPF to get better milage, however removing it and getting a custom programmer will give you the best milage improvments. there is alot of warranty stuff you have to consider before doing the DPF delete. my dad wanted to keep his warranty so he just bought a superchip and that picked up his milage a mile or so per gallon (its a 3/4 ton with 3.73s)
