It looks like it is leaving ok, the body slowly separates from the back tire, the nose wants to lift but it goes back down fast. So yes adjustable shocks will help. More converter may help it leave too depending where the peak torque is .
I'm only going to do shocks and leave the converter because i drive across the state and don't want excessive heat in the trans. I'm putting different heads on next year and pretty much leave it in the 12s.
