Honestly I put my left foot on the brake, right foot I press the throttle slightly maybe up to a 1500 rpm, let loose of the brake and slowly start pressing the throttle down til I hit the floor . You don't want to mash the throttle initially. Takes a little bit of practice but your 0-60 times will start coming down
I did a 0-60 run once in my blue car........with launch control. Yeah, wheelspin bigtime. Haven't tried it in the hellcat yet....it blows off the tires at 65.
