Hey guys great site, lots of info. I've read until my head hurts trying to deside what program or delete kit to get for my truck lol, I know this has proberly been ask to many times but I did not find it, I have a 2008 F 350 SWR, SB, CC, 4x4 Auto 6.4 that I bought new in the first of 2007, it now has 60000 on it with no problems, but as you know fuel mi. sucks, maybe 13 empty about 10 with a farm tractor behind it. Sounds like I maybe able to up that about 3 mi. a gals. I not needing the HP so much sounds like any of the kits would be more then I need, it does good now, so I am just looking for fuel milage and towing a little, doing the lest damage as possible to the truck, I know anytime you up the HP its harder on things, but what would you recommend, I see Spartan, H&S, KEM and do I need the delate pipe or the two pipes I guess? Just like to keep it simple so I can understand lol, what do I need to order to do what I want, and not spend no more then I need to? love to here what you would get? Thanks for any info.
