I'm getting around 20 in my 2002 Auto 3.8 V6. I know some have got up to 26mpg so I was wondering what I can do to increase the MPG or is it a crap shoot? I have done a complete tune up with a new K & N air filter, so it's not that. I was wondering if the previous owner put some kind of performance chip in it. Does anyone know where I would look and for what? Any other tips would be helpful.
