Where is my gas going?

Use a digital gauge and check the tire pressure. With a wide low profile tire you might not even notice it being toward the low side. Try it for a week with 32psi (if not already there), and then a second week at something closer to the max sidewall rating.

Consider an ecometer or scangauge II. You don't think you are driving hard, but the near instant feedback may tell you otherwise. With some practice you can get used to coasting with the terain along your route and see your trip average Mpgs start going back up.

Also as the weather gets cooler you will drop a couple Mpg. Look at your route and see if you can find a way to be on the side roads a few extra minutes before hitting the freeway in the morning. For the winter consider blocking the lower grille below the bumper.

I actually have them set currently at 32 psi, using my very expensive gauge at work. (I'm a mechanic) I tried closer to 40 and it made the car a little too rough. I used to run 45 in my Subaru but it wasnt as uncomfortable as this car is at that PSI. I have to admit I dont do much coasting because my drive consists of mostly hilly windy backroads. And when you get off the throttle it takes forever to get back to 45. I equate this car to a small motor with a large turbo at very very low boost lol. I just wanted to make sure there wasnt something wrong with this car. Our Motis at work cannot connect to my car so I cant see fuel trims. is there any software for our cars?

Subarus use a program called open ECU where all you need is the free software, a Tactrix cable and a laptop to see everything and tune. My tuner used it reliably to tune my car at 21psi with 565cc injectors and still keep the IDC at around 75% and optimal AFRs.
