[QUOTE="mdrc347, post: 9789477, member: 87305"] Don't do it with a pulley change. Just run the most aggressive pulley setup that is safe for racing fuel at all times, and tune the car on 104 octane (or your fuel of choice). Then have the tuner pull timing for pump gas. You can store multiple tunes in the handheld. Then simply load the race gas tune at the track and the pump gas tune on the street. Simple. Running alot of boost on pump gas isn't an issue if you drop the timing to compensate. To my knowledge, 104 is the best you can get in unleaded. Leaded fuel will screw with your oxygen sensors.
