Is there any reason not to do this? I have a stock 86 T, and I was thinking I could buy Sunoco FR and turn up the boost for a couple of days of fun, then turn the boost back down and go back to 93 octane. Sunoco FR is 96 octane is unleaded, oxygenated, and they claim performs well in turbo motors, plus won't foul o2 sensors. I keep an old piece of wire or paper clip on the turbo puck so I can twist it off, adjust the boost, and twist it back on. Typical West Virginia, but there is no duck tape anywhere on the car. And here are the specs on the fuel: http://www.racegas.com/fuel/5
