54mpg on a run isn't awful, it depends really, how do you drive on a long journey? A steady 65mph will see a lot better result than 75mph, for example. Do you hang back 100 yards and let the traffic brake and accelerate at random while you cruise, or do you sit in the middle of it? Coast down early to junctions still in gear?
Failing that it might be worth checking out your maf, i lost ~10mpg when that died. If you're still not happy reduce the frontal area by lowering it.
