Let's get a list of the best free things for better mpg and performance!!!!
 

I no cleaning map and iat sensors and stuff work awesome I just want to no any other things I need to clean or modify to get the best out my truck :tu:

air and fuel filter, tires inflated properly, alinement, running cleaner through your fuel system, (i use dexron atf), basic maintenance like lubing what needs to be lube and changing oil. the number 1 thing that controls your mpg's is your right foot.

Are there any other sensors cause the map and iat did a awesome increase :tu: What about really cheap turbo upgrades ??? I heard the new model turbos run better and are fairly cheap ?

Stock tires.

cold air intake.smarty jr programmers and turbo back 4'' exhaust

i dont know of any other sensors that will help MPG'S. What do you mean by new model turbo? the one for the 6.7?

the exhaust and intake will give you give you very little IF ANY. the programmer might help and also might not.

I thought we were talking about free stuff?
How about stealing fuel out of sleeping truckers gas tank hahahaha just kidding.
I run waste jet fuel and it doesn't get any freer than that :choochoo:

Someone said the newer model 5.9 has a slightly bigger turbo and it's fairly cheap to swap along with a 2nd gen manifold
