But sixth gear would get better gas mileage right?
And first thru fifth are probably higher numerically,
and closer together than stock right? Wouldn't that
be better for 1/4 mile performance?
GM blows

 encompass 99% of every aspect of vehicle operation and properties. Anyway,
 when running a corvette for top speed (stock vette by the way) and using
 all 6 gears, the top speed actually occurs in 5th gear, this is becuase
 the torque required from the engine to spin the drive train is to low at
 that point. So from the simulation the corvette would actually SLOW DOWN
 when it shifted into 6th, and according to the "while" loop used by the
 program it would then down shift into 5th gear and accelerate again.
 
 If you havent got the power to use it, why get it.
 
 But it would be sweet none the less!
