I have a 2011 f350 srw crew 4x4 6.2 gas,and I average 16mpg with camper on,and 18 to 21 unloaded.everything is stock.till warr is up cant do any mods.when it is want to do air box,over drive frm camping world,and a pro charger on engine,belt driven external unit not a screw blower .has any 1 heard of these? they will really wake up your gas engines.
I would do exhaust headers and exhaust before doing the pro charger. I have talked to a few guys on the FTE Ford forum that have had them, and they do add some power, but require a but more fussing than most wanted.
The other option is to talk to Mike at 5-star tuning. He custom tunes for what you have and want to do. The 5.4 and 6.8 guys love his tunes. Also many of the 5.0 coyote guys have great luck with Mike.
I personally have a 6.8 V10 with a Whipple screw-type supercharger. It is not inter cooled. It also has the Banks headers, monster exhaust, banks air intake with K&N filter. On the highway I have been able to pull 14-15 with 4.30 gears and stock tires. I live on an island now, so no freeway driving. All country lane 34-45 mph and town streets. My fuel milage is 7-10... But I also have a problem with the right foot being to heavy.... With all the low gears and performance goodies...it's just too fun!
