Well, the inline pump, e85, and tuning netted that. The e85 allowed me to increase my timing by 7-8 degrees.
Other factors that may factor in are that I was already supercharged and elevation here is 5300 feet. Not sure if that matters though.

He's blown and if he was running methanol the gain would have been larger. Blown applications with alcohol always have gains due to the cooling affect of alcohol (latent heat of vaporization is over 2 times that of gasoline). Another benefit is that the alcohols contain a small amount of Oxygen.
Typically, if you have a low to medium compression ratio, you will see a very small gain vs. gasoline. As you increase the compression ratio of your motor, you have a much hotter charge that benefits from the cooling effects of the alcohol.

Seems the general consensus about e85 is that they will make more power almost always than an equal octane race gas assuming the fuel system can handle the demands. Something about the corn juice just doe not want to detonate. Numerous reputable FI shops will agree if they have alot of e85 setups come through to get tuned.
