roughly how much would I gain with the truck that I have in my sig?

I usually get about 16 no matter how I drive combination (about 18 MAX on the highway)(15 all city). My brother has a CCSB and he gets better mileage than I do (like 20 hwy). Which I think sucks. Should I get her tuned for mileage by Justin, or just look for a 3.42 or 3.23 rear end?

A 3.42 would probably help you more than a tune for mpg. But, most likely the problem is your right foot.

If your truck is stock, you should be able to to achieve over 20mpg on the highway with ease. 15 in all city driving sounds normal, though.

One thing I have noticed over the years is that I get 2-3mpg better on warmer days (65F+) than colder days(50F and under).

Lets be for real here... We did not buy our trucks to save gas!

I do about 21 on the highway @ 75 with the TC locked. In the city its around 14 because the tc never locks. Mods in sig.

I know, although I still get frustrated because even when I drive nice, I still get worse mileage than my brothers CCSB even though I have a RCSB (big weight difference)

I think a RCSB 2wd truck should be capable of 21-22 on the highway. no?

At a steady 30 mph, I get about 28 ...












































28 minutes to the gallon!

Yes, you should. When was the last time you changed your plugs?
