So has anybody actually switched out their gears yet? Did you run into the problems some GT owners have? Information and numbers are nice but some experience would be great to hear about...

If you want the best quarter mile speeds, perhaps we should look at speed at peak horsepower in 4th gear:
Speed = (5,300 rev/min)(60 min/hr)(1/1.00 4th gear)(1/3.73 axle ratio)(0.0013387 mile/rev) = 114 MPH (you won't get a trap speed this high with a normal V6)
Speed = (5,300 rev/min)(60 min/hr)(1/1.00 4th gear)(1/4.10 axle ratio)(0.0013387 mile/rev) = 104 MPH (much more realistic trap speed for a V6)
So to summarize:
Auto Street: 3.73:1
Auto Strip: 4.10:1
Manual Street: 3.73:1
Manual Strip: 4.10:1

Swapping your gears out will also require a reflash to correct the speedometer reading, am I corret?

I have an auto with a few mods & I'm wanting to do a swap. Torn between 3.73 and 4.10. I may supercharge later & I wonder if that should affect my choice of ratios. I wonder how top speed will be affected, although I care more about acceleration than top speed. Seems like my car tops out at 120MPH now.
