30mpg

Is anyone really getting it? I kept hearing that people were getting 30+MPG with the 03-04 LB7s so I bought my 03. I'm getting 24 but would like to improve this, how many MPG can I really get?

The best I've had was 22.7 but most of the time it's 20-21. I'm pretty sure If I'd keep it at 65 I could see 22 quite a bit.

Let me know what you want for it if you're selling for real.

If you think gas is going to give you anywhere near the power and capability for that kind of economy you have another think coming.

By the way how you figuring that 24 MPG?

Do you have stock tires

Are you using the DIC to figure it or are you doing it by hand?

Good luck with what ever you decide.
