Thanks for the feed back guys, dyno was done at unigroup.
First import, still learning about all of these things. didnt add this before but he seemed to think that the ecu was reading the o2 sensor wrong, it was pumping in fuel even though it was getting plenty. I know i keep brining o2 sensor up but he said it will more than likely be the issue behind the economy issues (i am struggleing to get to 300 city driving and even cruising on the highway i am bearly making 400km to a tank, that was on a good week).
I will also have a chat to him about the fuel pump now that you have bought it up, and i assume you say that purely bassed on it not pumping enough fuel through the system, hence running lean.
Apologies for lack of understanding but im still learning learn.
Regards,
Dan
