At about 80mph, it's turning around 2100 rpms. I have the tire and
handling package on my 2001. Gas mileage is good. 16.5 in town, up to
23mpg on the Interstate.
I think driveability kinda suffers with the 3.92. First gear is really low
and the truck just doesn't drive as smooth as a truck with 3.55 gears when
driven "normally". The 3.92 kicks butt when roaring around town, but when
I want to putt, it sucks. I'm looking forward to wearing out the 31"
Goodyears and throwing on a set of 32" Kelly Safari MSRs so it'll lower the
ratio a bit and have a little more bite.
