    No issues, but the engine will run cooler and a little more HP with 97

    Like the 458 it is good to have 97 - 100 as Mike said. I just use pump gas and a premium octane booster to each dump tank. There are several boosters that are really bad for the engine in the long run. Spend extra for a better one. Far cheaper than race gas and still a drop in the bucket in daily track cost of the sport.
