All I have heard is that a locked torque converter physically links the impeller and turbine, which changes the converter into a mechanical coupling. The result is no slippage, and virtually no power loss. Most people say there isn't a whole lot of difference on the track but a big difference on a dyno. thats all i know of, hope someone else will have some more/better info.
