no boost until 4000 rpm's
not getting boost until i get to about 4000 rpm's. usually i feel it kick in about 3200 rpm's then all of a sudden it just started kicking in late. vacuum hoses and check valves are all ok. also blow off valve doesn't release as much air and is quieter.

That what I am thinking...

Do you hear a loud klunk right when you pass 4,000 rpms?
