I believe I will eventually go this route... With the possibilities of Hydra EMS it will not be that hard to accomplish this. Granted my compression will not be stock... the boost numbers will be up there for balance.
E85 is only available at one gas station here (around D.C.), but that won't be a deterrent. Well I guess it will be a concern when going on long trips... will have to plan more carefully. Not sure how accurate this is... but this is what I used to locate stations around my area:
