So hard to diagnose over the Internet. Could be many things.
Would start with the easy stuff first like boost leaks and checking all the pipe work ect. Best to get a mapper to do a diagnostic check.

Check the dump valve and vacuum tubing, also general leaks in the intake system. I believe my dump valve is causing unstable boost for me too so I've bought a HKS BOV that uses the boost pressure to hold it shut rather than a spring like most.
