I've been at this game for a while now with mine.. started off with 500km/80L (16L/100km) around town.
I've read hundreds of posts and articles, done just about every mod under the sun that could potentially reduce the consumption (snorkel, needle valve, egr block, remap, 3" exhaust, maf clean..) and have managed to bring it only slightly down 15l/100km.
I've not given up yet and still got a few things to try, which is meant to improve it again slightly, such as the air box mod.
But having said all this, I now drive the car how I like.. slow/normal/hard, OD on/off, and makes little difference to fuel consumption.. I still get my 15l/100km..
The biggest difference I've noticed is on country roads. Where I used to only get 14L/100km, I'm now getting 12.9L/100km or 620km/80L... and this is with the car fully loaded, overtaking at will, up/down hills.. So I've learnt to live with it around town, but still hopeful to reduce it further.
...forgot to mention, swapped the fuel filter at 70k, it feels like it made a small improvement...but need a few more tanks around town to be sure.
