I really don't like the idea of underdrive pulleys. It gains you very little, and can cause serious reliability problems.
Something to keep in mind is that the manufacturer is put under a lot of pressure to optimize mileage. If there was anything easy that you could do to improve it, it would already have been done (for newer cars at least). If you find something that works, there is almost certainly a tradeoff somewhere.
