yeah, thats about normal. if you're extra worried you can check your spark plugs and make sure the intake is free of build up. the only real strength of the turbo engine replacing a larger engine is that when you don't need the power, it will use less fuel (idle), otherwise it uses just as much as anything else that produces the same power.
completely different animal, but im running about 70/30 highway/city and getting 24.5-26.5mpg. 220hp/tq summer i will see 28-30
what kind of rpm is the engine turning at 55-60mph?
