i agree with Brian. but also what are you running that bullydog on?
maybe if you foot is quite heavy (as is mine) you would actually benefit from keeping that on a really low setting unless your doing highway cruising.
i found doing that worked the best when i only had my banks
also check out your air filter unless its one of those new fancy ones it may need a good cleaning

maybe check tire pressures, air filter for cleanliness, you have a new fuel filter, has this been going on for a while, maybe bad batch of fuel in the tank

Is your mileage hand calculated, or are you using the computer estimate?
