I was at a forum last week for work (I work in Oil and Gas). They touched on this being in the works. They pointed out that the bug auto manufacturers claim it will cause damage and they might not honor warranties. From what the "experts" at this forum stated they believe gas stations will have pumps with 10% ethanol (or less) and pumps with 15% ethanol.
I would hope this is what happens, but I guess time will tell how this works out.

I love how the EPA keeps doing **** to lower vehicles' gas mileage. Sure. The air is a little cleaner, but we are burning more fuel. They (the EPA) have pretty much fucked the whole diesel community with their requirements of DPF systems on new diesel trucks (since mid-2007).

i can see it possibly increasing performance, assuming you are tuned on e15.
you could make more power if you can get more timing in the tune without knock/knock retard
but you will *technically* be required to use MORE fuel to achieve the same power.
so a rescale on your injector pw or fuel tables may be in order to make sure you A/F is still dead nuts, and then see if she can take a little more timing, then double check your a/f with the revised timing table.
thats the theory tho...i literally dont know if 5% increase is enough to mandate any of that tho, maybe someone with some tuning skills can elaborate.
