Just to throw my $2 in here and my experience. I decided to put in a blend of ethanol. I'm on a stock tune and i used an online calculator to figure my octane numbers.

2 gal ethanol = 105 Oct
17 gal e10-91 = 91 Oct
19 gal blend = 93 Oct

Now i don't have dyno numbers but i definitely can say that there is more torque. The engine runs smother, sounds smother and my incline 1st gear start is less jumpy.

I used torque app to watch my AFR before and after and i would say the car leaned out about .50. Knowing the factory tune is rich, i figured a little leaning with ethanol would work out well. So far my mileage hasn't lowered.
