    my mpg really haven't changed since adding my mods. list in my sig.

    and if you just put the battery back on the avg starts form 0 and has to work its way back up. if your in the gas a lot local it will never get past 10 or 12.

    I can send you the tune I am running now I know I need to increase timing but I am wondering if the loss of mpg is due to me removing my egr when I installed my headers I had a leak after at the egr tube that's why I removed it

    Are you basing your mpg off of the DiC or are you actually doing the math and calculating it? 7 seems low

    Driving aggressive, plus in town driving will quickly kill mpg.

    And codes thrown??

    I drove 5 miles per day, got 10-14 in town and 125-160 miles per tank in the winter and 200-220 in the summer.

    ummm....stop driving like an ASSHOLE! should improve your MPG significantly. you arent even getting 7MPG if you are using a 17 gallon tank driving 7 miles/day; 7 days/week...you are getting like 3. no way that is right.

    This. If you are driving 7 miles a day, then 7 miles times 7 days is 49 miles. 49 miles divided by 17 gallons is 2.88 mpg. If your mileage was that bad, you would know it.

    These cars need the open road to see higher MPG numbers. Cold + city + lead foot = low teens easy.

    I am mostly going by the dic after resetting it and continuously driving I found that it also take the time idling into it's calculation I believe it's because of the time I let it run at idle for cold start 20-30 min a morning I know I am getting around 15 in town

    Of course it takes idle time into consideration. When the car is idling it is using fuel....

    I just got my car on the road and took it for a hwy drive and it was 15+. got to some back roads and had some fun it quickly dropped to 8. and just driving in town its around 13. So i sumize that as long as your drive with your foot up its ass you will continue to see that kind of mpg
