Post your best 991 Turbo performance numbers here

Not anymore. We need some new rules on that and Vbox ain't it. The Vbox data won't always match no matter how much you claim it will.

sample rate and the vboxverify software platform. But many have had success in tying out at their local drag strips and most recently at airstrip 1/2 mile events as some now employ engineers to set up traps there.
But lets not lose site of the fact that the vbox is doing the same thing in my car as it is in your car and any other car so the best attribute of it as a tool to measure ones performance before and after modification - like a dyno - to provide some data on whether improvements are gained on a road/track and not just on a dyno. Plus the fact that pertinent slope data and elevation (plus GPS/location and date/time are also saved within the dbn file).
So lets be happy we have such a tool and that Robert has spent so much of his free time writing vboxverify with absolutely zero personal gain for all of us to use. We know it's not perfect. And as was discussed in length on my 60-130 thread when I just had the GIAC tune only and did the 6.6 run, there are some variables under our control (I.e. Location , slope density altitude, gas/octane) that can have a significant impact on the results.
One last thing. We now know that both vbox and 1/4 mile time slips can be faked. Carlos did it and Madsex seemed to figure out how to it on the vbox. So we now must maintain a healthy level of skepticism with the risk of being attacked like Scott was by Carlos. Reputation and transparency are everything. And if someone seems to be hiding something let's call them out.

William, given the recent events I can understand how one would be more skeptical these days. I know we have had many debates about the vbox and I recall your issues with some of its abilities particularly with
