The Truck is a 2007 f250 SRW all stock except PHP FICM, PHP rollback VXCF4, Edge Programmer set on performance setting always
This is no towing and its mixed highway/City driving. Everything is hand calculated for mpg.
Before the Edge was installed I would see 14 at the very very best.
After Installation of the Edge set on the performance setting I was getting 16 at 75 mph. Cruise was set the entire time for 380 miles.
After PHP FICM my mileage stayed about the same (15.5 mpg) and only ran one tank through before I performed the rollback to VXCF4. My mileage then seem to go downhill overnight after that. The best I have seen is 11.4 mpg after running 3 tanks through.
Is there other sensors I should check? No lights on the dash. Gonna swithch to synthetic oil tomorrow see if that helps at all.
