Been doing some tests on my gsi this week. Been driving very calmy not booting and im getting 40mpg. Which i think i very good. So i though i'd c what it did when i floored it and kept it floored from 30 right up to..? dropped and levelled off at 7mpg. That explains why when i boot it even if not for long, i can watch the petrol gauge move faster than the rev counter lol.
Wonder what a standard GSi will drop to, has anybody tired it. Also can any1 better 40mpg?
