Traction Control
Have you driven your C7 with TC turned off? I have read a couple of articles in a magazine last week that turning off TC, especially Stingrays and Grand Sport models, significantly improves acceleration and performance. What is your take on this? Obviously one would have to be very careful when doing this, but for experienced drivers this may be a way of having more control, performance and acceleration.

This sounds like one of those urban legends that people believe right up until they take that famous right-turn into the forest that Z06s are known for without TC on.
Leave it on.

If you're talking straight-line acceleration, I seriously doubt it's better w/ TC off. I don't care how experienced you are. A computer is always going to have a better reaction time than a human.
People often feel the car has more power with it off because the wheels are spinning, but that doesn't translate to going faster.

Yes, agree. Even with TC on in Tour mode, I still see a fair amount of wheel spin, but the system seems to gently modulate the amount of power delivered to the rear wheels, until full traction is gained.

Fortunately where I work there are several nice long service drives with little to NO traffic. I've played around with the TC on and OFF and did the 0-60 times many times on different days and temps. Average times either way 4.0-4.2, best time 3.8 with TC off and 4.0 with TC on. Biggest factor seems to be Temp, tires, and surface composition. On concrete, warm tires, PSS OEM tires brings for me; consistent 4.0 - 4.1 0-60 times both on the PDR and the DIC timer. Honestly, Launch Control seems to be a tad slower always (4.3 - 4.4) so I rarely use it anymore. Maybe on a prepped track it might work better?
On new blacktop (very smooth) WOW, either you torch them with TC off or run slower with TC on, (4.3 - 5.0)
Sorry for the long dissertation but in my opinion at my skill level (low) on non-prepped surfaces the car is very consistent at what I would say is 4.0 to 4.2 w/and without TC on/off.
I'm sure a light mod, tune etc. might bring the car consistently into the high 3's. JMO with more 0-60 runs that $$ to replace tires LOL.

In Portland Oregon with traction control on the best I could ever do 0-60 was 4.0. I am living in Lake Havasu now, and consistently get a 3.8 and 3.9. Must be these cookie cooking temperatures here for the pavement and tires.

I envy both -- Lake Havasu is beautiful and consistent 3.8-3.9 times is excellent. By the way, I go to Laughlin a few times a year for vacation, both are nice areas.
