Dear Atif,
XE 95 have Toyota Carb based 2E engine. This engine does not return good fuel economy, no matter how much you get it tuned, it won't cross 10-11 mark. This is what you have to live with.
If you are really concerned with fuel economy, then better swap it with a 1.3 EFI 4EFE or 1.6 4AFE (come with JDM Gli).
