I'm assuming the STI just rolled up on the Z, lined up a "race" and beeped his horn to play with him and then after a second the Z driver probably said "F it" and hit the gas. I will say however with the 370Z 7AT there is about a 0.5-1 second delayed throttle response. However, if you use the paddle shifters to drop a gear or two the throttle response is much more instantaneous. Keep in mind though this is easily fixed with a tune for the 370Z. I'm going to assume the new 9AT will be more responsive from factory and if not a tune will fix that.Im sure Nissan is well aware of the Supra being underrated. I was hoping the Z would be underrated in turn. That was a pretty hard pull after getting jumped and that car is the automatic at that. Its hard for me to hear now ATM, but it seems the Z took a little time to kick down.
