jus blowin smoke
What would i have to do to get some mileage out of our fleet of 6.7 trucks. Right now theyget 12 mpg on the hghway and have yet to see it get better with one reaching 100000 miles. Heard alot about the delete kits what would be deleted and which kit is the best. Id like to see at least 15mpg out of our 3 trucks. Input would be really appreciated guys thanks!!!
 
Make sure you have a friend at a dodge dealership then start taking stuff off becarefull though HS performance has a great programer out once you put 5 inch exhaust on and and delete the EGR stuff.
 
i have a 09 6.7 with h&s xrt it lets you get ride of dpf and egr with no problems and im getting 26mpg hand calculated my dad had a smarty with dpf delete and sold his smarty to buy a xrt if that tells you anything
