Innovative tunes... Mileage?

[Gunjumper]

I have a Livewire running the extreme tune with dpf/doc delete and a drop in AFE filter. Hand calculated mileage is only around 13 mpg. Only picked up about 1 mpg since delete/tune and gambled on the warrenty. Will Erics' tunes help with better economy? I'm hearing that a higher HP tune will result in better mileage, so long as you can keep you foot out of it. True? I'll pay for the tune if it'll yield some better mileage for me, but not if it's going to be just for power alone, I have enough to do what I have to do. Any Innovative tuned 6.4's out there?

That is what i get with sct extreme it is usally around 13.3 and i have the older version of IDP extreme and i get 15.2.... This is hwy with 3.73 and stock 20'' and with speeds of 70-75 mph... So i use IDP for DD and SCT extreme for towing my 33' long 5th wheel and i works out fine... Towing with the sct extreme only gets me around 10mpg but it acts good and crispy...

Man i just got my sct and hope my mileage is better than that. i was really hoping for closer to 18 or better.

Nope... The lie-o-meter will tell you 18-20mpg's, hand calculated comes out to 13ish. Good luck, I've pu$$y footed around for several tank fulls and 13 is all I could get. Tried like heck to keep the boost down and the RPM's below 2000, 13 all day and all night. Innovative???
