Steve, your time and speed is almost identical to my G8. I have the same issue in the middle too. What kind of 60 ft's are you getting?
Are you on street tires, or have you added some DR's for the front? That solved my Flex launch issues by cutting spin on front. Of course it may be more needed on Flex as most of the weight difference between SHO & Flex is in the back, where it hinders by keeping rears hooked up, and allowing fronts to spin more which frequently caused my TC system to shut car down to prevent AWD damage.
I have been using Hankook Ventus 20" for 2-3 years now, every summer and have neer had any traction issues.
My 60ft with the 2013 is now 1.73... Always under 1.80.
2013 do lainch better, but with my current tuning, the car is still slower than my 2010.
With the downpipes and the 2013 being supposely faster, I expect it to be a high 11' car at 117-119+ mph car.
I hope that Livernois will crack it soon!
