Just to conclude the work done with the 4.10's on my L, we played around with a few things, got it running great. With the chip and maf, lowered rear, etc, I was pretty impressed with what the gear change did do.
However, I did switch back to stock. It just didn't feel comfortable, the revs were just a little high in places, and my cruising RPM was a little weird (hard to explain).
I think I still have alot of take off power using the stock set-up as is anyways. I just want my L to still have that "Daily Driver" feel.
Cheers
