C16 on a car not tuned for it?
From http://en.wikipedia.org/wiki/Octane_rating:
It may, however, allow you to turn up the boost safely, without worrying about knocking.
Using a fuel with a higher octane lets an engine run at a higher compression without having problems with knock. The power output of an engine depends on the energy content of its fuel, and this bears no simple relationship to the octane rating. A common myth amongst petrol consumers is that adding a higher octane fuel to a vehicle's engine will increase its performance and/or lessen its fuel consumption.
It depends how much you put in. Its actually possible to LOSE power from running race gas if you are not tuned for it., unless your current tune has a lot of knock in it. The best thing you can do it i throw on 2 gallons or so on top of half a tank and crank the boost up 2 more psi.

just use 100-103oct and go have fun.... C16 is leaded ...and unless u want to waste the life of your o2 sensors by "seeing what it would do" ...i wouldnt ...that's an aggressive gas....works wonders when you're tuned aggressively...more timing...lower egts ...etc
