Looking for a good high-speed stall torque converter

[Catbox_95]

Does anyone have any personal first-hand experience with aftermarket torque converters? I've read about the IPT billet torque converter, but haven't been able to find much information on anything else.

I know there are a lot of factors that go into torque converter selection, but the basic of it is I don't build boost or make power until about 4,200 rpm and the stock torque converter is killing me.

I already have a TCM program which really did help tremendously, but now I need a higher stall torque converter. Any personal experience or advice would be appreciated.

Yeah I've been to Sinister Speed. They give so little information on their products they may as well just show a picture. I guess I need to contact them.
