DFP kit from Spartan Diesel Tech?
6.4 MPG I am new to the forum and it seems like I am getting the best fuel economy at 13.7 and thats all around driving. I will keep checking back to see how you make out once it is installed. I am paying 4.19 per gal and would love to better my economy. I have an 08 250 crew, 20 in wheels...- jguitarfly55
