Updated - 379.6 miles to the tank. 175 cruise, 200 city (a LOT of gridlock traffic). I suspect easily 400+ miles per tank without massive traffic. 25.14mpg.

The 6AT loves 60mph. This is ~140 miles of nothing but 60-65 with no cruise control or braking.

Tires set to 38/40 cold psi.

The 17inch tires have a smaller circumference and will show that you have gone 2% further when compared to the 19inch

I installed headers the other night and my MPG increased about 20% so far this tank. Additional power and gas savings. I am pretty happy so far. Deleting second cats would probably increase mpg even further. Going to try that soon as well.

I should tell my gf that if she loses a cpl more pounds it would help my overall mpg. Then when she dumps me ill save about 115lbs, either way its a win win.

yeah, I am still on my same tank but have been in traffic driving, a BMW cruise, and roughly half a dozen races up to 110. So yeah, total asshole driving lol. The car's estimated average 38mpg went down to 30

Arggg yeah. I got a 175 mile trip on Thursday and am wondering if I can make most of it on whatever is left in the tank and restore my shitty mpg. I just want ONE tank average to be like 30mpg, then I can say my car is running correctly and let the topic rest.
