I'm running a complete stock 7mgte and i keep hearing a fluttering sound from the diverter valve, does that mean it's not opening all the way? i'm pretty sure i don't have a boost leak because the psi holds constant. any ideas?

If you have the stock air box intake more then likely your bov went out and you are hearing compressor surge.

This is very harmful for your turbo. If this is indeed what your problem is

^Yup. If that's your stock BPV (bypass valve) it's toast and needs replacement.

You can use a Bosch BPV as the easiest replacement. That's what I ended up doing and it's been great.
