There were accusations that the dyno graph posted of the 773 wheel horsepower world record pull did not belong to the vehicle in question, that the pull was not run to redline due to tuning issues, and a host of other ridiculous theories were propagated from people reaching for whatever negativity they could. Well, here is a video of the car setting the record on the Dynojet dyno. Additionally, one can hear the clutches slipping and see the issue is not wheel slip on the dyno or tuning related during the WOT pull.
The transmission is currently being built to handle whatever amount of torque the Vortech YSI is capable of putting out and another pull will be made once that is complete along with a visit to the drag strip. Fanboys can continue to spread negative rumors if they like as Gintani is too busy raising the bar on the E92 M3 S65 V8 platform in the mean time to notice.
