"Converter change" how much improvement...

Mopar XHD springs and CE adjustable shocks all the way around with the adjustments on 50/50. I put the shocks on before I bought the drag radials intending to play with them to see if 70/30 and 90/10 would hook better but never had a chance to play with the adjustments before I got a deal on the drag radials that I couldn't pass up. Once I put them on it hooks real hard as long as I warm them up a little.
