    Not usually, taken from a point of efficiency, you can get more out from what you put in, but at the same time if you are constantly wringing the extra power out of it, you will lose some.
    It could be best thought of as slightly amplifying it's current economy, so if you are a hard driver, and usually in the lower mpgs compared to the average, you'd use more fuel in gaining the extra power.

    If you are an MPG chaser, with long runs and better than average consumption, you may see a small increase from efficiency, but in general, there is no obvious change reported by non turbo tuned cars.
    (Turbos chasing big power may have very high consumption by using extra fuel to avoid detonation, but this method isn't used in Normally aspirated engines)
