Angry boost problem

So I installed my COBB 2.5 and Iím having problems holding boost at WOT. If I run threw all the gears at half throttle it holds boost. But as soon as I punch the throttle in at any gear it goes up and down from 12 psi to 16 psi, but as soon as I let go and go half throttle it holds around 15 psi. I have a VF 30 it comes with a upgraded wastegate actuator I think thats the problem or what could it be.

Could be any number of things... but most importantly check the BOV, vacuum hoses and wastegate.

Take the bov apart and relube it, or adjust the spring tighter to test it.
