Did you test; the V6, or the V8? Cause they were two different transmissions....
And keep in mind they can recalibrate the transmission from car to car. They 'fixed' it in the Corvette from 07 to 08, which produced a noticeable response increase according to the 'Vette guys. And they're also playing with shift response in the Camaro to drop the V6 0-60 from 6.1 to 5.9.
