Replying to 540 specific trouble

I tried some 5's today (snow day) off a jump we made and the first time i got to 3 and have a bad habit of opening up but i pushed myself to keep going and only got 450 and ate it into some soft snow. However the second time i tried to huck a little more and i ended up doing almost a bio 5 but not coming out of it and landed on my side at 450 again. i have made a few threads in this cult already sorry, but any tips? or suggestions?
