Fuel
I have read many tests on high octane fuel, and unless the car calls for it, then it does absolutley nothing, Unless you are running a very high compression engine then you don't need 114 octane. Average rule of thumb for boost to compression is that for every three pounds of boost you increase one full compression point, thus making 12lbs of boost on an sc motor with 8:1 compression or so, you get 12.1 compression ratio under full boost, that is why this car requires nothing less than 91, i personaly use Sunoco 94. So unless you start running really high compression stay away from the race gas.
