On the FiTech E85 question above, The answer needs more information.
I think they are they saying the peak advertised HP level will be 25-30% lower because the injectors size? Not that the engine will make less power on E-85 (upto the injector size limitation?)
E-85 carries fewer BTU's per gallon so it takes more of it to support the same amount of HP. For E-85 applications its always recommended to upsize injectors at least 30% for this reason.
This is true for any system.
FYI not all injection systems are E-85 compatible as it is corrosive to some degree. Chrysler use to sell Flex Fuel Spirits and everything in the fuel system was stainless steel for this reason. Even the valve guide seals were unique as the fuel would attack the regular seals.
