Converter upgrade worth it?

Ok,thanks. It runs great, just sluggish acceleration from 20 to 40 or unless push hard enough to downshift, then it's like switch on. I'll make a call or 2 to a converter company.
Call more than 2 converter companies and find out what they recommend for you and what you intend to do with your car. Make sure you give them ALL the specs that they ask for. B.S. them about anything and the converter will not perform properly. Only a high stall builder can really tell you what you need. Just because a certain converter stalls perfectly in my car, doesn't mean it will do the same in yours, unless your car is identical to mine in everyway. JMHO
