blended fuel....
A gas station that I normally fill up at now has stickers saying that up to 10% could be ethanol.... does this effect performance or anything else in our high HP cars?

Yes, Less energy in ethanol so a tune for it will/should give better performance, but because it contains less energy you will burn more of it. What brand do you use? E10 is Mercedes Benz approved.

E10
E10 is 10% ethanol and 90% unleaded gasoline, a fuel blend covered under warranty by every automobile manufacturer that sells vehicles in the U.S. for every make and every model of automobile. Many recommend its use because of its high octane and superior performance characteristics.
Ethanol is currently blended into about 46% of America's gasoline, the majority as the E10 blend. Each state determines whether gasoline needs to be labeled if containing ethanol, so if you're in an area where labeling is voluntary or not required, it is not always possible to tell if the gasoline contains ethanol. Ethanol blends are offered extensively throughout the Midwest and are becoming more and more widely available from coast to coast.
Because ethanol has an octane rating of 113, adding 10% ethanol to gasoline raises the finished fuel's octane rating by 2 or 3 points, improving the fuel's performance.
In some cases, different percentages of ethanol are used instead of the 10% blend. In California, for example, all gasoline contains 5.7% ethanol. E85 is a blend of 85% ethanol and 15% gasoline that is mean for use in flexible fuel vehicles (see below).
E10 is safe to use in small engines such as motorcycles, lawn mowers, trimmers, boats, personal watercraft, snowmobiles, ATVs, and many others. Manufacturers understand that a considerable portion of the gasoline sold in this country contains ethanol and ensure that their products are compatible with oxygenated fuel.
