I did a huge amount of conversions with these kits. Were they a bolt in and go deal? NO. Some were closer than others, but anytime you do a conversions, there is going to be issues. Some cars are tougher than others.
I think the problems may have started when they started to build their own transmission instead of just modding the Tremec. I suspect that Tremec caught wind of it and cut him off. Just saying. It's only my opinion. And now that I'm not "in" the industry anymore, I don't care what anybody thinks of my opinion.
