Nah mate, smaller tyres (IE going from 35 back to 33"s) have to turn faster to give you the same vehicle speed.
The only way to do that is spin the engine quicker.
To slow the engine RPM for a given speed it's bigger tyres OR change to lower diff ratios (not higher) OR change gearbox ratios.
I would suggest that the 4.11 diff and 35's are probably the go for 4WD'ing with the 4L80 ratios... but... probably the 3.9 would be better for cruising however I am by no means an expert.
All I do know is that the yanks swear that 1750-1800 ish is the sweet RPM for cruising with the Chevvies they have in their big pick ups.
Bottom line is it is always a compromise
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

Ian, how does your Diesel/Gas setup go with the Chev? Was only recently talking to Highlander about that mod. Where do you mount the gas tank and how big is it? How does it affect your fuel economy?
