Can't Chirp 3rd gear?
Why can't I chirp 3rd gear in my 2005 Z51 6 speed coupe? And don't say learn how to drive! I have had many other cars with less power and have been able to chirp 3rd gear but in my C6 all I get is a little sqweak noise, and it's not coming from the tires. Does this mean my clutch is no good?
Thanks

One way to check if they actually are spinning is to leave TC-on and just accelerate with a throttle squeeze in 2d. Then watch the DIC on the 2-3 shift and see if "TC-active" appears.
That technique worked on a C5Z to prove that the tires were breaking loose on the 2-3 at about 70, the 3-4 at about 100 and even the 4-5 at about 145.
Of course, TM rears its head on strong shifts in a C6.

I wouldn't expect to be able to chrip 3rd if youre tires are in good shape. Those supercars grip VERY well. I may have chriped 3rd on a couple of occasions, but probably when the pavement was a little cold.
If you really want to chirp 3rd, then you should POWERSHIFT

I'm sure this has a to do with torque management.

Chirpping fourth!!!
My 05 Z51 has a fairly fresh set of Toyo Proxes T1R's on the rear, which grab a whole lot more traction than the Supercars ever did. They also make a lot more squalling sound to let me know when I'm pushing it to break point in a turn. Point is: you're probably spinning slightly with those rock hard Supercars but dont hear as well. If you're hearing the belt squeal when shifting hard, you doing a good job! Be sure to turn off tc and ac for the best power! On mine it makes a difference from barely hearing 3rd to hearing fourth at 100mph!!!

I think I have proof that you are 100% correct about the non-Z51 being faster. My 01 Z28, when I shifted to 4th at the top end, I'd run 112. When I just let it bump the rev limiter in 3rd gear it would run faster at 112.7. Then I upped the rev limiter and I could run through the lights in 3rd gear at 113.75. All the Z51 guys swear that extra shift doesn't cost them, but they are all living in their little Z51 Dream World!

I need to be in 4th gear for a decent 1/4 time [mine's a Z51].
I tried the 1/4 and the rev limiter hit in 3rd, right before the finish line.
