Converter upgrade worth it?

Update. Disappointing, the new converter does flash to 3k as specified and works well that way. The problem is from idle to 2500 or so I lost alot of throttle response, if I didn't know better it's almost like transmission is slipping. The engine has to rev more for the same amount of motion as before. I'm not saying anything wrong with the TC because it does hit at 3k. Just maybe not want I needed. The car was way more fun to drive before. I will be putting old TC back in.
