i do 36 miles a day some traffic/motorway/dual carrageway, if i dont boot it , about 26mpg, if i do , then about 22mpg, on a long run about 35mpg in sport mode, have remapped to 170bhp but no mods other than monza, esseesse etc . i generally use 5500rpm in each gear, as turbo drops off after that, so dont often see shift light , so get about 200ish on a tank of V
