I know where he is driving and I have watched him drive around campus. I can believe he gets fuel mileage that low. Nothing but stop signs and trafic lights around there. You can only cruze at speed for 30 seconds or less before you have to stop again. Campus is right in the city. I see him driving it pretty gently each time I see him around. My car probably wouldn't do any better where he drives, and I get 21-22mpg each tank because I get more cruzing time to and from school.

We can datalog fuel trims and a few other parameters to see if it's our tune killing gas mileage, but that's uncommon. Our tune usually helps mpg's a little...

Let me know.... our Street and Performance maps are usually really good with gas mileage. Either way, make sure to drive it the same way next tank.

I've still got 3/4 a tank left, I'm going to wait till its gone till I try it on the stock tune with regular. I kinda doubt that its the tune, its probably just the area I'm driving. I'll be sure to shoot you a PM if I do get noticeable better mileage without the tune though.

You guys must floor it everywhere you go once you put gears in. Me and my ex drove to Nashville at the same time but in separate cars. Hers was an 01 gt with catback, o/r H, TB/Plenum and sniper tune with stock gears. Mine was fully built, blown and 4.10 gears. Both had cruise set at 75mph and both used the exact same amount of gas. 1/4 tank for the 90 mile round trip.
