Yep one of the few 08's that are out here..... Also for the record, Manual KK's come with 3.21 gears...
I haven't measured my mileage lately, but last summer, I was averaging 16ish city with my 4 inch lift, E rated BFG TAKO's. Mine also weights more then 4800+

Am I reading this correctly, or did I miss something? I'm not sure if I am following this is the correct order because I too am dying to hear how it works.

So glad I read through 5 pages to see no reply about the Jet Chip.
I have figured my mileage a few times since I got the Lib 4 months ago. I end up with between 15 and 17. I assumed when I bought the thing it would get similar mileage to my 2005 4.0 Ford Ranger, and I do. I also don't keep up on my tire pressure like a good boy should.

No replies about the chip, this seems to be a mileage thread.
If big tires give you such bad mileage that it's bothering you, why don't you get a set of street tires and rims for going to work, and the put the big ones on when you hit the trail?
Or maybe you could get a civic for work!

Not to rage or anything, but why on earth does every JET chip thread always lead off into the distance about a different subject?!

I'd like to know what the benefits are of installing this chip-
and- I get about 10.8 miles to the gallon in the city.

It's even funnier, Super Chips is advertised, and they don't make one for the KJ.

Jet Chip
I'd like to also know if the Jet chip works. I do mostly city driving but I don't go into work until 1030 pm when there is no traffic so I am driving 40-50 miles per hour with very few stops. Coming home in the morning most of the traffic is going in the other direction so there isn't too much stop-and-go. I also drive 10 miles each way so the engine is warming up properly. I was getting 15.5 mpg and I just put in a K&N drop in filter. I got 16.2 mpg on the first tank but I am only 1/4 of the way into the next one. Still have the crappy stock Wrangler ST's on it (225-75-16). Also there is some additional weight over the stock 4x4 with OEM skids- I put an Aries brush guard on it. I think I should be getting slightly better mileage- I am driving at sea level on flat terrain using 87 octane. Any info on the Jet Chip would be nice if anybody with one could post it. I also pulled the roof racks off and will only put them on when I need them.

Judging by the response I'd say what has happened is what everyone on here says happens. The computer ends up compensating for the chip which after a while negates your add-on.

Pretty much. Unless we can find company to reflash the computer then its almost useless. Works great I bet for the butt dyno. Just my 2cents
