clean injectors
change air filter or clean if is K&N
change spark plugs
after you do all that and if you still have mileage
change tranny fluid (dont know if that may help also)
swap maf with a good working one to see if that makes a difference
was the timing belt ever changed
clean the gas filter in the gas tank
probably change coil pack
is overdrive engaging?
other than that I dont know, has the car given you any idication that something may be wrong, idling hard? etc
correct tyre pressure <- can make a big difference
what rims are you running?
a friend of mines have that same engine with manual and she does get 450, before with auto it was 400
