Torque Converter Advice

Purchased a 9" converter a while back hoping to improve 1/4 mile times. Wanted about a 3200 stall. I got it and the performance improved slightly but was not what I was hoping for. Ended up installing a transbrake to help spool up on the line. What I found was that I could only brake the motor to 2500rpm and about 5 psi. So I sent the converter back in to get re-stalled. It is certainly looser now... a little too loose. First time on the brake it flashed up to about 5200 rpm before I let off the throttle. The manufacturer asks me how much torque it's making but I don't have any idea. There is a chassis dyno about an hour from me, but with the converter this loose I cant imagine I would get accurate results unless I locked the converter. Would this hurt the converter? I'm getting tired of yanking my tranny out but I want to be able to launch at around 2800 to 3000 rpm. Any advise???
 
Ummm, whose converter?

I've locked single disk Vigilante and Protorque at the track and on the dyno.

425 HP approx.

Not a ton of passes but 15 a year or so locked for those converters.
