Torque Converter

I have an 11 inch converter in my car and I am really not happy with it. It functions just fine but
it's is not a high performance type of converter. Stall is 1600 to 2200 ACC 11 inch unit. It wasn't expensive and I've had it for 10 years with no problems at all.
I e-mailed the ACC guys and they said they could restall it for me for a minimal amount of money as they don't recommend a 10 inch for my combo. I also contacted Lenny and he called here today while I was working so I'll give him a call to see what he says too.
Is it ok to restall a converter? How is it done?
