I doubt your car sucks.... There's just a LOT of factors, which you mentioned, that can and will dictate your final numbers.
You're exactly right, not every transmission is created equal. The ZL1's automatic will lose less through the drive train than a normal automatic. Why? Because the way it's built and prepped. The same can be said for a manual, pending the style of clutch.
As for your trap speeds, don't let the MPH numbers fool you. Again, if the manual comes off the line spinning, his or her MPH numbers will be greatly higher than yours. That has nothing to do with HP, but the fact that the manual wasn't able to hook up. A car that launches hard, hooks up, and has a low 60FT time, will usually have a low MPH compared to a car that spins.
But you are correct, regardless, you should have ran it in 4th Gear. Good luch with future runs and keep us posted.
