Question: 2011 BMW 328i gets horrible mpg - how to improve?!

Car is leased by employer. I took over lease when my car was stolen (he didn't like the car). Dealer put 19" run-flats, which I changed out to Michelin Pilots. Dealer also put sport exhaust but says it's not the full-on sport pkg with suspension, etc. Supposed to get 18/26mpg. I've been getting 12.5 in LA and 22 hwy. I drive like a granny to try to get the numbers up. Dealer says the computer tells them all is well and they can't do anything else. Well, two of my neighbors have the same car and they get 7mpg better and more. Help! Also, what tire pressure would you hold? Door is incorrect since the dealer changed out 17" std for 19". Thanks!
