Just to clear things up:
Speed Engineering has a Magnum DI TVS2650R with Katech fuel system on a C7 Z06 Corvette that makes 1002 RWHP

Mike Swanson has a TVS2300R with the Lingenfelter fuel system on his Camaro SS that makes 996 RWHP

I'm not aware of any others.
To date, neither has had an 8-speed capable of handling the power that the cars make. ATI has recently released an upgraded 8-speed, Speed Engineering will be going that route. Not sure what Swanson has choosen.
