I specifically asked my tuner about this when we updated my 93oct and E85 tunes into a multi-map setup.
The reply was that running FF on a custom tune for straight pump gas or full E85 won't provide any improvements. The major benefit is when running variable pump/ethanol blends, as the FF integration helps adapt to situations where the E-content varies greatly (ie - running OTS E30 tune and mix a tank to E50).
