flash convertor?

My new dyanmic will 'Flash' at 3800rpm but only really slip to about 2,800rpm under casual driving. Meaning if i'm sitting at the tree (strip) and revving to whatever rpm it seems to like...say 1,500rpm and NAIL it at 'green' it will let the motor wind to 3,800rpm before moving the car. Sorta like driving a nail with a hammer. A say stock converter (usually 2,000ish rpm stall) is like tapping on the end of a nail with a hammer....will take forever to get the job done, right? A higher stall will be like winding up and driving it in with one blow. Theres a term for it to be able to do that, but still maintain highly streetable charateristics such. It's known as a 'tight' converter meaning it doesn't slip much under regular driving, and it being a high quality converter will do that, and be able to flash at 3,800rpm for me without worrying about converter slip at cruising speeds. Hope that helps/makes sense lol
