What boost controller are you using? The boost spike and then sudden dip shows that it isnt reacting fast enough. Usually dips at your peak tq area are alarming but it can be seen by the map logging that your boost controller is at fault for that. Never the less it can make tuning difficult because its hard to tell the difference between too much timing and pressure drop from the sudden wastegate opening.
Do you have a gain control on your boost controller?
Im not trying to be negative, the rest of the graph looks smooth. I just think the car will feel more controllable and more powerful if this small detail can be overcome.
The boost controller seems to settle down just fine too after max boost is reached so I dont think its a solenoid problem, I think its most likely a setting on the controller itself.
