Didn't boost at all. Even when I accelerate I would stay below in vac on the boost gauge (or at zero). I've changed the oil, changed the spark plugs, changed the stock filter, seafoamed the car, did a compression test, properly inflated the tires, etc. and I still get this gas mileage. If there is something wrong with my car then I'm completely missing it somehow.
