This is kinda hilarious...I have had my share of cars over the years, from supercars all the way down to the original Suziki 4x4. My favorite was my old '87 VW Syncro 4x4 pick-up truck, and this thing was so underpowered I had to time my passing from waaaay back (like 20 car lengths) just to get by. On the other hand I have taken that damn thing into spots where a mule could not get in/up.
I have been used to downshifting one gear and trying to pass and have been left wanting to get by the intended car to be passed. As I have gotten to know my jeep better, I now tend to downshift two and punch it and it does get up and go. It is no speed demon and that is not why I own it but I have been happy with it's power and also with it's economy, given what it has for a power plant. Would it have been nice having a larger engine? Yah, but I don't think it was in the cards given the fleet fuel economy goals at the time. Given the drive to decrease pollution across the board on all manufactures, I don't think we will see too many gas guzzling muscle cars like we have seen in the good ole 70s (circa).

when I bought mine, I was very impressed with the quality paint job and fit and finish of the body. My favorite vechicle to drive of the many I have owned.

paui4m Super. Thanks to all for the warranty input!
I'm fine with it around the city and most times. On trips through the hills the constant downshifting and engine noise can become exhausting, though...

The key is how crooked is your dealer!! A tuner should only void a warranty if the tuner caused the problem and it is up to the MFG to prove that the tuner caused the problem. I have been through this with a tuner on my Diesel truck and GM told the dealer to fix my truck under warranty even though the dealer did not want to. This is the same thing for any mod we do to our vehicles, it can void the warranty, but the mod had to cause the problem...

I have a SuperChip, bought it after putting 33 inch M/Ts on my 09 unlimited. Running the 93 octane program gives me more power then I had with the stock 31 inch tires. In town I have plenty of acceleration, but on the highway even slight hills make my autotrans drop out of overdirive. I have 3.73 gears and am in the process of re-gearing to 4.56 gears.

Manufacturers and dealers are doing their best to make money; this includes saving money where they can.
Part of their approach is to discourage shadetree mechanics, mod-fever, and any other activity that blemishes their perfect design.
In fact, it's illegal to mod your vehicle like we do in most other countries ---- and the manufacturers love that...

So, ask yourself that question again.
The short answer is that each dealer will look at it differently. Some will cover you and some won't. It all depends on how they word the work order and what their dealer-culture is all about.

He's got one axle in the garage with 4.56s in it and is waiting for funds to regear the rear; he'd also like to lock it at the same time rather than pulling it apart again.
We need to find the boy a job too; he's still looking since coming back from Germany.

Ozarkharleyguy I just got an 2010 and I understand the concern over the lack of power. But partly I think its good to remember you can't have your "kate and edith too." This wasn't designed to be a hot rod. It does what it was designed to do very well. My Mustang GT with nitrous was terrible off-road and on rough terrain where the gearing was low. I complained in the Mustang forum about how bad it was off-road. So I imagine there are a few things you can do to make the Jeep a little quicker but remember it may not produce the results you seek and there is a trade-off for everything you do. Rots-a-ruck.

back on topic. regearing will make all the difference in the world. I have a friend with an 07 2dr RUBI and he never had anything positive to say about how his jeep ran until he regeared it to 4.88's. even on 35's he says he can drive it like a hot rod and get the rear tires to break loose in turns.

can't think of the company name right now, but you can do the hemi conversion, end of discussion!

JIMBOX Regearing counts for EVERYTHING, when you increase the tire size, over stock issue

Lockers and a lower crawl ratio counts in mud/snow/shale (rubicon)

Lack of Power

I had a Chevrolet Tahoe before I got my Jeep. The Tahoe sounded cooler with the 5.7 liter V-8 but it was speed limited to 100mph so it wasn't any faster than my jeep is now. I can live with the lack of horsepower because the Jeep can get me through places the Tahoe just could not go; and it is way funner to drive. I don't know what a Hummer drives like but I have no complaints on my Jeep. I do have the factory tow package so I don't know how much of a differance the tow package gears make.

Yah, looks like you got the skinny of it. The power plant is what it is. I use mine off road as much as I am able to and it performs there very nicely including crawling real slow when necessary even as a stock jeep, it does well.
