Looking for advice/insight on car

I bought a converter from turbo action. It was a 3200 and no joke the stock converter was faster. I pulled it out and sent it back. Then called PTC and ordered one built for my car. It went from 2.0-2.05 60ft to 1.80s . I can't leave over 2k due to traction. Once I get new drag radials I believe I'll get a lot better 60ft times. I think some issues your having might be in the converter.
