tightening the wastegate got rid of most of the flutter for me. It also made my car hit target boost. My boost used to jump around alot, now the boost is steady (16.4psi in 4th gear according to AP) until it starts to taper off towards redline.
Try tightening it a turn or two and see if it helps. If you start to spike, undo a half turn at a time until it stops spiking. The AP is definitely accurate enough to notice any spiking.
