i noticed this in my 1,8 astra.
cant wait for the tunes to settle in and everyone reports on the fuel economy.
the day after the tune i noticed a 50% increase in fuel.
a month later i noticed a 30% decrease in fuel usage.
the tune probably settled quicker than a month, but it was a month before i had a decent drive to be able to notice the difference.
some people may freak at the 50% increase, (like i did lol) but what they have to understand is that increase will only last a week or so...
(im sure it depends on kms travelled not time),
and after that its the 30% decrease for the life of the vehicle!, or till you sell it.
lets say you usually spend $1560 a year on fuel ($60/fortnight), with a 30% decrease your annual fuel cost is approx $1000, saving you $500. in just over 12months time the tune has paid for itself!
