Wow that is pretty bad, I never owned a std Gen 1, ordered it with exhaust and Tune and on a bad week with a track day I would still get around 400 to 450k's and the best I got was 720 using 49.7ltrs coming back from Bathurst. We have just bought a new Gen 2, 4 months ago and we are getting 600k's plus easy and is stock std....
