I think you want to use the 10% stuff within 90 days or so, which should not be a problem. The alcohol in the 10% can absorb moisture, but new cars should be designed to deal with this. If the gas is old it may effect the octane, I think so that could be an issue with your mods.
You could run a tank by tank comparison to see if you get better mileage with the straight gas and factor in the cost, you can google and see if there is a straight gas dealer near you, it might not be worth it if its far.
