Well it's been a rough summer for gas mileage.

The wheels and lowering happened about the same time so I think one negated the other to be honest. I still need to get the ecu retuned again, just haven't had the down time to send it in for a reflash.

I work all day in the NC heat so driving back and forth to work with the AC off just isn't an option for me personally. The heat has also been severe enough that I removed the grill block and am now 100% full airflow. All of these things have led me to poor mileage.

I am starting to keep track again of fuel mileage as I was getting very discouraged when seeing 15.xx mpg overal per tank so I stopped keeping track.

The 75% upper grill block may turn into 100% once the average daily temp goes below 70. I'll just rely on the lower grill to do the trick. Should be fine. I am also going to be actually accomplishing the belly pan on the bottom too.

She looks much better than the day I got her.
