Re: 4.56 or 4.88...that is my question.
Well I'll drive it 'til Sunday and report back. Sunday night it gets dropped off for the gear work; but I've got a long haul this weekend into western Maryland so that should give me some good data. Lot's of hills.
My feeling is the 12 is going to be pretty spot on...it immediately dropped to 10 and some change after the 37s and stayed there. The fact that I'm two days in and it's still reading 12 is encouraging.
...and there was no babying it, once I noticed the added 'umph' I stayed in it harder then usual. It was a little 'refreshing.'

Well I hope you do get 12 mpg... just after having 2 H2's and about every possible combination, I have yet to average 12mpg even when it was stock.

Re: 4.56 or 4.88...that is my question.
Simple things to improve gas milage:
remove roof rack bars and offroad lights on the roof (there was a study that this alone can drop your milage by 10%)
remove spare tire
remove extra weight not needed
install k&n air filter and keep it clean
inflate tires to 5%-10% under max air pressure and keep an eye on them
use mobil 1 gas saving fully synthetic oil
put the car in neutral when coming to a stop or going down a hill
With my 08 h2 I can average 13.5-14mpg in the winter and higher in the summer mostly city driving. I can hit 16s on the highway in the summer time. This is different than the older h2s as it has 25% more horsepower and a 6 speed transmission but all these things add up.

Well, I ain't worried about it.... I ordered my Duramax 6.6, allison transmission and transfer case yesterday.
I won't be installing them probably till summer but the quest begins.

Yeah, I'm gonna need it... I seem to be problematic when it comes to conversions and the such.
