What where you trying to gain by strapping the front down? After taking another look at the video I think the lack of front suspension too low of air pressure & coming out as aggressive as you did lead to you bouncing. And if you watch close the drivers side back tire quits spinning towards the end. So, either your locker/limited slip isn't working or the trans was slipping. If I were you I would leave the front suspension stock, air the tires up a bit and try to come out a little smoother to see what that does. Just my .02 cents.
