Do you have an auto or manual? Also, what kind of tuning device are you using? You really need some sort of a logger to determine if you car is running "good."
But things you can check now are items such as spark plugs and wires. Check your timing, make sure your brakes are fully disengaging, do a leak test, check out the free mods if you havn't already done them or replaced the parts. You'll see the most results though most likely in tuning your car to get the most out of your setup.
