    Ok since my last post it didn't get rid of the rich fault. The car is currently in with my mapping guy and he said he can see it pulling my fuel trims back straight away. Really he is baffled and so are my! He knows now what he has to do to sort it but really he said that he shouldnt have to do this, he has done this mod many times before ( 3" maf, 225 injectors, k03 hybrid with 225 internals).
    Can any one think of any reason also why it would be doing this, open to all suggestions.
    Also has anyone ever came across fake injectors for these cars, I.e China import copys, I bought mine off a scrappy on the rail so I find it highly unlikely!
    Thanks
