*Slap forehead* i kept looking at unlabled charts thinking that there the same for auto/manual. thanks for clearing this up. i appreciate the replies. im also gonna give driving w/od off a shot. i heard that its good to turn off od when on streets and to turn it on on the highways... have you heard anything about that?

I have the 2010 with auto and the #`s you are stating are correct. I run 33`s
Im waiting for the super chip to be ready this should solve some of the problem but the 3.8 is a dog anyways. my 09 X had the same issues and the super chip cured most of that. you could also go with the AEV power module. its about half the price of the superchip.

G'day
I have a 2007 JK - it came with factory 3.21's & I run 33' MTZ's - it could barely pull the skin of boiled milk LoL

on 3.21's @70mph I was doing 1900ish on the Tacho
after regearing to 4.56's the tacho now reads 2850 @ 70mph!

2nd gear now on 4.56's is approx the same rpm as 1st was on 3.21's

slip it into 4low and 4.56's give 1st a real rock crawler feel.

I also got rid of the rear exhaust muffler and fitted a straight through pipe - Jeep sounds great now and I think I picked up a little more down low HP.

I totally recommend changing to 4.56's
the jeep has gone from sluggish to Yee Haa

If you ever come to OZ Ill give you a drive on real outback road! and you can experience the awesome difference.
cheers Hunty
