All your going to get are wild-assed guesses. No way to answer this, not enough info. Too many possibilities.

Did you ever get the PCM tuned after this just having the motor rebuilt? Was the cam installed in it before or during the rebuild? More details are needed here as mentioned. Codes?

Well your description doesn't really make sense, we can't help you out if you don't go into full detail of the problem.
Just saying "my car at 5k rpm kinda bounce back and goes up to shift??" doesn't make any sense, what can we determine from that?
