Take a close look at the directions on the can of boost. Most will claim only a single point or less of boost per can per small tank of gas.
I tried a large can in a truck I had with dual 19g tanks. There was no difference in ping form the tank with and the tank without, there went $4(?) a few years ago. other web pages confirm this impression, to get more than a point or two you have to spend $15 $20 for booster. Why not just use premium.
Course you could always buy race gas in barrels, but it ain't cheap either.
Good Luck,
