The stock ECU should automatically retard the Timing when it sences the different octane. Most modern cars will do this. I ran race fuel in my STi when it was bone stock and ran a 12.9 Vs. the 13.4 that I was running with out it. Race gas definately makes a difference. Just try to get the pump gas as far out of it as possible. My buddy used to never put more than a 1/4 tank of 93 in his Evo just in case he had to race. He would run to his house and throw some gas in his car. That and the weight loss from runnin on fumes is a big difference. I think fuel is like 6lbs a gallon or something close to that.
