Believe it or not, stock ecm parameters will adjust for race fuel. If you have bolt ons, you can expect 5 to 10 hp from what i've seen in my experience. If, however, you're pumping out 90 or 100hp more than stock, be sure to shift to a colder heat range spark plug.

No No No!!! Most race fuel is HIGHLY leaded and will clog your cats within a day. Sunoco makes a 110 octane Unleaded fuel for about $7 a gallon.
