Yeah youre bringing it up with the revs to high, if youre not letting of the gas, then youre hitting rev limiter and losing power, and never reaching bp. What gear are you in? I think you might be taking to long on the clutch/throttle blip too, it should be about a half second from roll off/clutch/roll on, all basically at the same time, this way you use momentum to yourr advantage, which lets you pop it up quicker with less rpm. Its all technique man, just keep at it. I recomend practicing popping up quick to bp(or whatever is comfortable, youll get better as you go) over and over, once you get that, riding them out is cake. Start small and just work at it, at your own comfort level. Dont forget that back brake!!
