That's the exact setup i have and its not bad at all. I have good acceleration and it runs good rpm's at highway speed. I'm sure it would be better with maybe 4.10s but definitely not worth it. I plan on swapping gears when i go to 33s.

that is a very good web link Frank! i found that 4.10 with 31 inch tires will be almost exactly the same as 235/75/15 and 3.55. Very good info on that site!!
