Any map cure the horrendous mpg? I'm guessing there are some fueling issues, as between 55 and 60 mph you loose 10mpg (goes from 40mpg at 55mph to 30mpg at 60mph), this kinda suggests it overfuels ALOT at this stage (60mph)
TBH I bought mine knowing they were crap on fuel (and I love it too much to care), but if there was a way to "cure" this minor ill, I would get it asap.
