It's difficult to tell when the car loses grip unless you corner. Using LC I cannot tell I am losing grip in the first 60ft but the AP definitely shows me it does. Your Vbox data shows it more pronounced I think. Look at the flat spots in your acceleration curve in the first second. You got a 1.8s 60ft time and the flat spots came when you had really high lateral acceleration and then a big dip, look how lateral acceleration spikes twice and dips during that first half of a second. I think you were losing grip when the acceleration dipped and your acceleration curves shows that. Here is a similar run that I made but with a better ET and on just the stock PZeros with a 1.66 60ft. This was captured back in January on all new stock PZeros.
Anyway, according to Vbox, your car is probably already as fast as mine but I have a Cobb/ByDesign Stage 3 setup. You can read all my mods on the sig line. LOL! Time to get rid of this car.

We've got a cat-less exhaust on our .2 and it's crazy how fast that car is! Seem like they are ALWAYS in boost. Even with you're off the throttle, sometimes the boost gauge shows 5-8 psi...it's weird, but awesome!
I took a customer for a quick ride in ours last week, and his first comment was "no way this car is not tuned!". Can't wait to get some software in ours once the break-in is over.

But sometime either this week or next week, the stock exhaust will go back on for a baseline dyno test.

Ha ha, I hear you the stock exhaust is awfully quiet. How many miles are you shooting for before stock testing? Try to get some v-box data too if you can, would be great to have more stock data points.

Pretty good for a stock car, it's about 60 more than my 991.1 was with just the exhaust.
The 991.2 Turbo S will be a whole new ball game because of the revised VTG's and some other goodies in the factory software (encryption, anti-lag, etc).
As with every new platform, we and GIAC are already hard at work on the new software which is in the early development stages.
