Increasing E85 Percentage

I fueled up the Grand Prix GT with six gallons of regular and eight gallons of E85 today, and everything is running fantastic. Does anyone else notice the engine runs smoother using this mix? Is it the higher octane rating - maybe the 3800 runs better on performance fuels?

Or it's the calm before the storm: my engine is going to die, and my fiancée is going to be none-too-happy, hah.

The smoothness may come from several things;

Cooler burn (if at stoich)
Lower peak cylinder pressure
Cleaner fuel system and combustion area.
Higher octane (significant if you were getting the knock sensor detune on gas)

Alcohol
