I wonder how the ZL1 will do when someone installs a torque converter in it for the 1st time... those CTS-V guys are saying the all get AT least a .5 decrease in there 1/4 mile times. When I do order mine, I am going with the auto for sure!
a smaller pulley change will happen as well, har har har....
BINGO!!! A stall will absolutely make ZL1 a beast. Throw some DRs on it, and it's going to humble many other cars. I'm curious to see if a lot of the calibrations are similar to what tuners have already been doing for some time.
