Move to a state where you can get sunoco 94 at the pump or fill up with a mixture of 100oct at the pump or run a mixture of toluene, as stated many times in this very thread.
You want 300hp? You run the required octane to give you the detonation protection that you need for 300hp. Its that simple.
Am I the only one that gives props to subaru for putting out an aggressive ecu in the usdm STi? Would you all be bitching MORE if it was the other way around? Yup!
