I've got the same question Kent. Did you get an answer yet?

I have been playing with mixing E85 on my Flex which is basically the same setup, you guys have a bit more flow potential on your DI pump than I do according to what I've been told.
I can run 6 gallons 91 E10 with 2 gallons E85 on my car with the 100 octane race gas tune I have but I don't have enough flow at the top end of 3rd - 6th gear. I had already installed a dedicated nitrous fuel system which is a 1 gallon fuel cell with Walbro 255 and boost referenced fuel pressure regulator. I have been leaving my bottle off and using my nitrous fuel system to spray fuel in addition to stock DI system at full throttle to compensate for lack of fuel on my stock system. This is working but I don't trust it completely. In the Full-Race thread I discussed it a bit as well.
For my car since I have an aluminum intake this is going to be my plan:
1. Weld 6 additional fuel injector bungs into the intake and install 6 injectors with fuel rails.
2. Control the injectors with a split second 6 injector controller.
3. Turn my nitrous fuel cell into a surge pump setup that is refilled off of the factory fuel system.
If that's not enough fuel to run full E-85 then:
4. Install Squash performance dual fuel pumps, utilize factory fuel line as return line and install -6 fuel line to front of car, split at firewall to factory DI and aux PI system.
For me I'm installing upgraded factory turbos (nobody is making a turbo kit for my platform yet) and should be at 500+ WHP by this spring.
Lots of FUN!

E85 in the 5.0 makes noticeably more power. I run it sometimes and it definitely adds hp and tq throughout the powerband. My gas mileage in town goes from 14 mpg with 87 octane to 11.9 mpg withe85 consistently. It's also around .75$ cheaper per gallon. I'm a fan in the 5.0 with e85. I've ran it in my 2010 Tundra and I feel it lost power and went not single digits mpg. Must be the high compression of the 5.0 that likes the high octane e85.
