Economy is great so far, drove from Sydney to Kiama and back, my average was 11.7l/100. Look, standard injectors to 80's, economy wise I cant see a change, it all comes down to the tune and the way you drive the car. I average between 350-400k's per tank, that day to kiama and back I got 470. For the same cost, you'd be mad goin the 60's.
