I had trouble with those once we reached a certain hp tq level.

Mine were a little loose with 600hp but not horrible. What I didn't like is that it never would couple well enough at moderate rpm so when the converter did lock it was violent and a huge rpm drop. There was no amount of trans tuning that made it livable. Ok for a weekend toy but that got annoying after a few hours of driving. With more power that got even worse. They were just too loose under normal driving, making lockup too drastic.

Hughes was the first custom lockup converter I've had that actually couples very well at moderate rpm levels so lock up isn't a drastic rpm drop and not nearly as violent. Almost stock like, but it'll flash up nice when you get after it.

It's a fine line of too much or not enough. I spent about $6000 with different converter companies in a short amount of time till I found something I'm happy with, performance good at the track and drives nice without violent lockup. Hughes, for me anyway, has been the best at getting it pretty damn close on the first try.

I do like tsp however in non lockup turbo 400 stuff. That seems to work decent enough. Maybe not coupled as well as a couple others I've tried but ok as long as you aren't making more than 600hp/TQ. That's another subject entirely with a whole page of experiences I've had with that deal.
