Hey, I have been searching tons of different threads trying to see with the mods in my sig if I could add a 10% lower along with LT headers? Or if the 10% is pushing it as far as 93 octane. Im not trying to run e85 or anything else, so I guess as far as horsepower goes my limit would be what 93 can hold. If its not possible to run a 10% lower than I would probably just port the blower. Thanks for any input.
