i get 30 mpg if driving carefully to from work (25 miles each way not in town traffic)
at my old job only 5 miles from home in town traffic i only got 18mpg. none of the STs have a an instant MPG readout, mine a '07 ( which is for sale by the way) and doesnt have instagt mpg, only the average, which you can reset at any point.
can get 350 miles to a tank if driven carefully, but where is the fun in that,
oh, the pops and bangs are normal, once hot and you acllerate under a lump of boost, let off, dup the clutch and then quickly blip the throttle to release a really loud ALS style BANG
