When you start throwing mods into the picture, everything changes and the whole discussion just becomes an endless circle.

I guarantee you the GT500 has TQ nannies in it's factory tune. How much further ahead will the GT500 be with the same mods? (aftermarket CAI and tune)

All said, I wouldn't mind seeing the 6R80 auto in the GT500. They are plenty strong enough to handle the power as has been seen with the 5.0. That would be the ultimate dragstrip dominator IMO.

That's cool bro, but that had nothing to do with what I was saying lol. GMRULZ simply said that there may be something wrong with car, such as an insane amount of torque management. I'm aware of the GT500 could get tuned, but I was only talking about the ZL1's current predicament as to why it is not getting the times it should be getting.
