Or you can power shift....but I wouldn't recomend that unless you have another daily driver to use incase yours breaks. Power shifting is keeping the gas pedal down while you do your shift. It will jump your rpms up a **** load once you put that clutch in but you won't lose a lot of rpms once you let it out. However it's hard on your daily driver since you are letting out your clutch with your rpms so high.
if you can do it well, it actually saves ur syncros because they don't have such a drop in the RMP to adjust to, as long as ur not revving it super high, it won't hurt your car too much, besides 4.6s are tanks..

I'm still trying to pinpoint what my problem was
like defcon said, and i said the syncro has a hard time adjusting to the sudden drop in RPMS from such a high RPM(6k) but you should be shifting at like 55-5700 like they said and powershifting also helps like that 1 guy said, but when i do it i only rev it about 5-700rpms nothing drastic, this might also solve your problem but i think you will be fine shifting lower without powershifting..
