"Low Band "apply question

I rode in a chebby that didnt have low band apply and it gave you that feeling somthing was wrong, every time the guy was off the throttle the car would coast and the engine would go to idle, then when he was back on the gas the engine would rev to meet the car speed, didnt seem right. As for dry hop burnouts after the water, i read an article from a trans or converter manufacturer that said the first launch after your water burnout will be the best your going to get, so dont do dry hops. I roll to the lights after the water burnout.
