[BiturboS4] Gear selection

I've felt the same need since day 1. I would aandon 5th (about useless),
make 5th = the current 6th, and have a taller 6th for simply maintaining 75
on level ground. Might eek out a % more in mileage. That's what Corvette
does (I know, way different). The torque curve is so flat on these that
there's little point to downshifting to pass on the interstates. I've moved
to the largest tires I can fit under there to up the final ratio a bit.

What I want to know is this... Has anyone tried to change the final
drive ratio to get wider ratios between gears? I find the 6 speed to be
a little close on the shifts. With an engine like this, I should need
6th until I get crusing on the highway. I find myself in 6th when on
some surface streets.
