Only mod that I have is a stillen exhaust, dealer installed. Any help? Any one with the same problem?

It's no BS getting over 20mpg, I've posted details on it, and I've even had as high as 26MPG on a 200 mile drive.

I call BS on you. I get 20-22mpg consistently. I drive 60-40 mix of highway and city. I do 70-100 on the highway. I dont do major jack rabbit starts from lights, but do a decent job accelerating from a stop. I do take it easy on the breaks and am great at anticipating red lights, so my driving doesn't have me breaking a lot even in the city.

I just took a trip where I drove from Atlanta to West Palm Beach via Orlando. I hit 100-120 a few times and most of the drive I was at 75-90mph. I averaged 80-85mph overall on the highway drive. I got 20-21mpg for the trip and I did that by checking the odometer and the gallons filled between fillups.
