FWIW Edelbrock says if you put their E-Force supercharger on an L9H you can't use E85 any more. I'm guessing the fuel pump/injectors/etc won't keep up with the extra volume of fuel to feed a blower with alcohol, even though it feeds the 6.2 just fine w/o the blower. Here's what the installation instructions say:

"91 octane or higher gasoline is required at all times. If your vehicle has been filled with anything less, it must be run until dry and refilled with 91 or higher octane gasoline twice prior to installation. Any failures associated with not using premium 91 octane gasoline or higher, will be ineligible for warranty repairs. THE FLEX-FUEL FUNCTION HAS BEEN DISABLED. DO NOT USE ANY GASOLINE WITH AN ETHANOL RATING HIGHER THEN 10% (E10). FAILURE TO DO SO WILL RESULT IN ENGINE DAMAGE AND VOID YOUR WARRANTY."

(Sorry about the shouting, that's Edelbrock's, not mine.)

I'm running my bone stock flex fuel in-tank pump with a Kenne Bell Boost-a-Pump and it's keeping up with my 75# injectors and has been for a year or two. I run E85 about half of the time.
