Obviously if it's leaded race gas that won't work since it will toast the O2 sensors.
There hasn't really been many requests for a race gas tune because E85 tends to work a lot of better since it offers not only high octane but also very good in-cylinder cooling. Also as far as unleaded race gas goes, I don't think anything more than 100oct would be of any use. And even with 100, I'd be surprised if more than 10hp gains (over 93oct tune) were possible.
