[QUOTE=edevlinThey said it should, and when I put in the racing fuel, the car did seem to run a little differently, seemed a little quicker with the butt dyno, and gurggled more when letting off the gas. When I ran it on the dyno, it looks like it picked up about 5hp with the racing fuel, so in my case it seemed like it was doing something.

Yes the car will run better and will have a slight gain in HP. But you don't need a full tank of 100 Octane to get this. All you need is a mixture of 100 Octane and 91 to equal 94-95 Octane. Your fuel mapping will max out at 95 Octane.
