IM a highway driver and just wonder gas mileage between the two gear is, I have exhaust, c.a.I., and chip.

 

I hate to sound rude, but nearly all your answers are found in the forum through search.


To give you my .02...
This will depend on many factors: Driving style, elevation, PSI, 2/4 DR, sh!tty gas or high grade, and other things.

But if you are upgrading from stock, expect a decrease in gas mileage.

I have 37's, 5.13's, 4dr, speed limit driver, 4500-5000 elevation, 30-31 PSI, 91-95 high grade, and I get 18.

 

5.13 all the way I get about MPG as stock

 

Yes I kne their had to a post some where else but I was new to site and need to kno quickly because their was a set on craigslist for sale, but I appreciate u guy let me kno.

 

Is it auto or 6 speed?

 

Use this to pick ur gears

 

It's a 6 speed and the chart u showed is helpful.

 

Some people I know who run 37's run 5:13's and say they should have gone with 5:38's. But they don't do much highway. If it's daily then 5:13's are good

 

The chart u posted showed the 5.13 with the 37 was in the blue block but the other guys and the the other post I finally found say 5.13 , so I'm picking up the gears this weekend for $450 saved me couple of dollars

 

Good choice. I got 5:13's for my 35's. I put them in this weekend I believe
