3 - At 70 mph what RPM is your engine turning? 2700rpm

4 - Are you using the AEV PROCAL or Superchips Flashpaq? Procal

5 - On the road what is your opinion of the performance? Handles good on road plenty of acceleration still.

6 - Off road what is your opinion of the performance? Does great Offroad

7 - If your fairy god mother came to you and said you will get any tire/gear package you want would you change and to what? I should have gone to a 37" tire and will this summer.
How is the 4:88 with 35's? Sounds like you won't have to regear when you goto 37's

1. 3.73's 5 speed auto
2. 33x12.5x15 BFG AT T/A KO
3. 2250
4. Superchips FlashCal
5. Tires and gears aside, the 3.6 is SO much better than my 07 with the 3.8
6. Off road I like the 3.6 better than the 3.8, but it's not nearly as big a difference as on road. Tires and gearwise it's not as optimal, but this is my DD and family vehicle, so in my case its a decent middle ground
7. I would change to a 6 speed manual with 35's and 4.10's. It's probably the best combo of everything, but since my wife can't drive stick, well, it's just not happening, at least until we save up enough for me to buy her a new WK2

Mistakes happen. Only reason I am interested in 12+ is the engine is a completely diferent animal.

6 - Awesome, simply awesome.....

7 - No, thought about going to 37" but it does everything I want and need and I don't have to mess with the drive shafts and lift

2850 Can't be accurate. That's higher than some running 4.88. Do you have a manual?

1 - What gear ratio are you running?

2 - What tire size & Brand are you running?

3 - At 70 mph what RPM is your engine turning?

4 - Are you using the AEV PROCAL or Superchips Flashpaq?

5 - On the road what is your opinion of the performance?

6 - Off road what is your opinion of the performance?

7 - If your fairy god mother came to you and said you will get any tire/gear package you want would you change and to what?

1 - What gear ratio are you running? ---4.88

2 - What tire size & Brand are you running?----Toyo MT 35x17

3 - At 70 mph what RPM is your engine turning?---3000ish

4 - Are you using the AEV PROCAL or Superchips Flashpaq? ---AEV ProCal

5 - On the road what is your opinion of the performance? ---performance is fine. Gas mileage could be better if I'd have went with 4.56. As it sits, I'm going to move to 37" tires with my pretzel axles and treat it like I did my XJ with a D35

6 - Off road what is your opinion of the performance?---like, it's pretty decent for trail running. My other Jeep has a 4:1 and it's better off-road but this one is fine (Mine's a Sport as I didn't want the 4:1 in this Jeep)

7 - If your fairy god mother came to you and said you will get any tire/gear package you want would you change and to what?---TIres and gears....hmmmm. I really like my Kevlars on my other Jeep (ran 40" and 38" now). I'd run a 35" Kevlar MTR and 4.56 gears.

Oh, my Jeep is a 2012 Auto. New head, fresh oil pump, fresh oil pump sensor and some new ABS stuff....(all courtesy of my warranty)

4. No
5. Great
6. No idea .... yet
7. Only if she came with a unlimited gas card, I would go to 35's or 37's and 4.88s

1. 4.10
2. 33x13.5 Irok SS (very heavy tires)
3. ~2500 (~2350 at 60)
4. Procal
5. Perfect mix. Great in town and on the highway (hit 21 MPG once - even with my mods - which is better than my best tank while stock). I'm a tad under geared in the mountains when I'm pulling my trailer... otherwise I'm very happy with how it's setup. Can consistently get 17 MPG with my trailer (17-17.5 without).
6. I don't rock crawl, so they're a little low for me if I go to 4lo - however I only need to do that to engage my lockers, otherwise I don't have issues.
7. I'm happy with how things are setup now. I'll go to 35s once these wear out, which means I'll likely have to regear at some point (if I don't put an LS in), but with how well these are working out I don't see it being a major issue. BUt if I do re-gear I'd like to try and keep the ratio the same as what I have now - if only to make the drive in the mountains with my trailer better.
8. Auto (this makes a difference as the auto in the 2012+ has a lower ratio than the 6 spd).

Here's my reply. Note that my rig is Ripp Supercharged.

1 - What gear ratio are you running? 4.88

2 - What tire size & Brand are you running? 37" Goodyear MTR's

3 - At 70 mph what RPM is your engine turning? 2750

4 - Are you using the AEV PROCAL or Superchips Flashpaq? Neither...using Diablo Sport Trinity

5 - On the road what is your opinion of the performance? Ripp Supercharged too. On road performance is great. City MPG around 16. Hwy about 18-19 at 70mph.

6 - Off road what is your opinion of the performance? Haven't been offroad much. I'm sure I'll be satisfied though.

7 - If your fairy god mother came to you and said you will get any tire/gear package you want would you change and to what? Wouldn't change a thing.
