I fell blessed if I fill up and the computer says 260 miles to empty, usually says 240...WTF

 

This is what I get also. This is why I have held back on a more aggressive rear gear.

 

Same here. 200 miles to a tank with almost all city driving in traffic (rarely doing the speed limit).

 

Ever since the SC install, I can't make it through a tank without dipping into the boost a few times. My best with SC installed is 20mpg, without it, 25mpg was about average for highway and some city included.
Considering my 1985 LX 5.0 got at best 17mpg on the highway when new, this is a bargain!

 

I get about300 with a stock 2005 GT except for the Araid CAI.About 70% of the drivingbeing on the hwy. Average speed is around 80 on the hwy.

 

Lately i've been driving @ around 18mpg. Most of it city driving... I am starting a job some 20 odd miles away, bumping the city - hwy to about 50-50 i guess. I wonder if I can break 20mpg soon. It has been a while since I did that. Generally I do 17-18. Last tank the 50 miles left notification rang at about 220 miles.

 

two weeks ago driving from SC to NJ, i got 26 mpg at 80-85 mph on a full tank!

 

I get about 225-240 and about 1/2 is highway

 

most of my driving is highway for work then some city driving. i usually do about 350 a tank but i let my friend borrow my car for a few days and now its 300....hmmmm, someones been driving hard

 

my guess is two fold... weight for one... and keep the price down...
