MPG downer

I don't have a exact answer for you but that's way off I'm getting 17mpg with 37s on the highway. Also is this hand calculated? If not then hand calculate cause the dash is always off

I've noticed that my mpgs have gotten better over time since tuning. Originally tuned in spring of '11, I got just about 11 mpg right after tuning. Since then, the mpgs have been steadily climbing to their most recent point (calculated after filling up the tank this morning) of 14.9 for city driving.

Calculating milage in the city is a waste of time you never drive the same traffic is different way to many variables

When I first deleted I got about 12.5 now I get about 14.5 mpg. It seemed to get better the longer i stuck with one tune. The latest tune from h&s helped. although my boost Is much higher than before. That's with a 60/40 mix and I drive gently but not like an old lady. I also have my LBF at 5. With the 250 tune.

Stock tires and suspension i was getting 18 average hwy hand calculated.....then now im seeing around 14 or so after the lift and wheels, tires.
mostly ran on the hot tune, performance tune.
You didnt say if you were lifted, or wheels tires. those two things individually drastically change the MPGs.
